    The thing is, even if some of the stuff is cheaper in the US, the fact is that the US minimum wage is US$7.25/hour (which is less than AU$7/hour at today's exchange rate).

    We're used to being gouged here.
    Just look at the prices for consumables in Japan and USA.

    $3.20 for a bottle of water from a Melbourne vending machine can go and get FIRETRUCKED.

    Yep, cost of living is atrocious in some places. Where I live, we're in the middle of a mining boom. Rental prices average $700 per week, for a 3 bedroom home, 30 years old. $15 will get you a 600ml Coke and a sandwich from the local Cafe...

    Here in QLD $1.80 is about average for a coke or $11.50 for a 24 pack.

    I think that's supermarket prices.
    I thought we're talking about a 600mL cold bottle of drink, from a servo, convenience store or vending machine.

    lol, another memory of Japan.
    Decision time: I could get a 500mL can of Coke for about AU$1.40...... OR at the other vending machine, I can get the special TWO cold cans of beer for an extra buck?

    Yes, vending machines over there sometimes have specials.

    Guys, This is getting way off topic.
    on topic: I'd actually prefer my foam in meters because I have a hopper clip that doesn't accept darts over 1.5" and also would like more rounds in my hopper and RSCB clips without having to reload.
    well thats just me.

    Some may say that 'this makes the foam more cheaper'. However, MOST wars are played on grass. Smaller darts are MUCH harder to find again than long darts.

    Yep, RSCB is a good point.

    I actually did a little testing yesterday and found that shorter was better. Don't bitch, this is my darts with my blaster. The 1.5" with snap cap and 00 weight, 2x 00weight and cut down tail silicone tip went a good 35' - 45' further than the full length with standard silicone tip. Probably more like 50-60'. This is what I found with my darts with my tips in my street at a certain time of day, for discussion purposes only.

    Pretty pathetic that I feel such a need to emphasize all that.

    Over all, I just found shorter darts better. 1.5" Works perfectly for me. Full length actually fish tailed a huge amount out of my Titan.

    That's the Mexican factor mate - you're too bloody close to the penguins!!

    Why not try using FBR in the RSCB's, as another more experienced member than myself has suggested?

    Yeah Mozart, they will fish tail out from a titan for sure.
    #2 split shot sinkers on a stefan dart blown out of a titan are crazy.

    I have full length darts fish tail from the octo. They have to be short, stefan length, with either 6mm bb's or preferably #1 split shot sinkers. I'm getting 120ft with the sinkers, and i'm about to upgrade the spring, so 140ft is on the cards.

    Hahaa, yeah man. I can't find any 13mm FBR down here.. Found 10mm and 15mm, no 13mm ):

    Yeah, they go all over the place, no stability with full length. I've ordered (sort of) some more 10mm snap caps, I'll just stick with those from now on.

    side note: I remember someone saying they would never break, ages ago. I beg to differ. Titmav has ruined (without the tip leaving the foam) five or six of the 15 I had left. One, the sinker actually came out, pushed it's way through the snap cap, lol.

    You can get the 13mm FBR at Clark Rubber by the meter. That's where I get mine. Ask for closed cell white foam.

    I use full-length blue foam with a plugged Titan, hitting over 400 feet angled. No fish-tailing at all. Weight of the dart is the answer, more so than length. Obviously, climate will have an effect as well.

    @Mozart - agreed on the snap caps, I've busted a few out of my Titan when they hit different material, mainly coarse brick/render. No issues with steel though, but sometimes the cap comes off, but that's due to the hot glue, and the cap remains in one piece (well, the few that I've found anyway). The post you're referring to was from Littlebro, and he was talking about war-legal blaster's. I'm yet to even damage a snap cap out of a LShot.

    You're not limited to using 13mm FBR with your titmav, as it's couplered. Get a small length of 10 and 15mm, and find a barrel material to suit.

    Yeah man, you're right. LShot wouldn't hurt a snap cap, Titan ruins them, lol. Yeah, same with the close quarters, I was actually shooting a Tek3 to pieces, lol.

    Meh, I kind of want to stuck with 13mm. Not that fussed. I'll buy some off someone on here if I need to. Thanks man (:

    Also if you were looking for 13mm FBR. Call up places for waterproofing. Found a place near me that sells 250metres for $45 (bulk only). Blue foam is much better though. I'm using 13mm FBR for BYO wars since I'm a cheapskate.

    If I'm reading SS right, look up why golf balls have dimples on them.

    The foam has tiny dimples in it like those on a golf ball.

    Engineers and scientists in the golf industry study the impact between a golf club and a golf ball to determine the ball's so-called launch conditions. The impact typically lasts only 1/2000 of a second, but it establishes the ball's velocity, launch angle and spin rate. After this brief impact the ball's trajectory is controlled entirely by gravity and aerodynamics--no matter how much the golfer hopes or curses. As a result, aerodynamic optimization--achieved through dimple pattern design--is a critical part of overall golf ball development.

    A smooth golf ball hit by a professional golfer would travel only about half as far as a golf ball with dimples does. Most golf balls have between 300 and 500 dimples, which have an average depth of about 0.010 inch. The lift and drag forces on a golf ball are very sensitive to dimple depth: a depth change of 0.001 inch can produce a radical change to the ball's trajectory and the overall distance it can fly. Dimples have traditionally been spherical in shape, but it is possible to optimize the aerodynamic performance of other shapes. The HX golf ball by Callaway, for example, uses hexagons (see image).

    Air exerts a force on any object moving through it. Holding your arm out of the window of a moving car easily illustrates this phenomenon. Aerodynamicists break down the force into two components: lift and drag. Drag acts to directly oppose motion, whereas lift acts in a direction perpendicular to motion (it is usually directed upward in the case of a golf ball). As you rotate your hand in the air stream, you vary the amount and direction of the lift and drag forces acting on your hand.

    A moving object has a high-pressure area on its front side. Air flows smoothly over the contours of the front side and eventually separates from the object toward the back side. A moving object also leaves behind a turbulent wake region where the air flow is fluctuating or agitated, resulting in lower pressure behind it. The size of the wake affects the amount of drag on the object. Dimples on a golf ball create a thin turbulent boundary layer of air that clings to the ball's surface. This allows the smoothly flowing air to follow the ball's surface a little farther around the back side of the ball, thereby decreasing the size of the wake. A dimpled ball thus has about half the drag of a smooth ball.

    Dimples also affect lift. A smooth ball with backspin creates lift by warping the airflow such that the ball acts like an airplane's wing. The spinning action makes the air pressure on the bottom of the ball higher than the air pressure on the top; this imbalance creates an upward force on the ball. Ball spin contributes about one half of a golf ball's lift. The other half is provided by the dimples, which allow for optimization of the lift force.

    Some of that vaguely brings back what I studied in my previous course, especially the boundary layer concept.

    Also:
    A smooth ball with backspin creates lift by warping the airflow such that the ball acts like an airplane's wing. The spinning action makes the air pressure on the bottom of the ball higher than the air pressure on the top; this imbalance creates an upward force on the ball. Ball spin contributes about one half of a golf ball's lift.
    It matters not whether the ball is spun with overspin or backspin, it will still generate lift according to the Magnus Effect.

    And this is evident in when a golfer uses a Driver. You generally only use backspin when chipping on to the green. With a drive, you're usually chasing distance, so backspin isn't desirable. Watch a few golfers teeing off, if they're any good, you'll see the ball start out low, and then rise. A bit like the arc of a frisbee.
