Replacement or additional springs for LS

hey everyone!
i've been scanning loads of threads and no one seems to cover what springs they use for modding their longshots.
I'm making this thread for people to post all of their spring replacements or additions including info on the spring and where they acquired it.
I'm gonna start off with an idea i had for an additional spring. I went camping on the weekend and a few of the tents had those guide ropes with a spring mechanism on the end and they seemed to be about the right length and slightly smaller in diameter than the stock spring plus they're cheaps so i am going to buy one of those guide ropes and take out the spring add it to my LS.
So thread is open post away

C-836 Bunnings Spring Replacement. I'd say this about the 3556443245677654th time I have told someone this.

added a bbb spring gun is beastly powerful now cant wait to angel breech it

sorry australiannerf i should have mentioned that my bunnings stock jack all when it comes to springs i checked em out and they were terrrible absolutely nothing the right size maybe bad day i hope so anyway i just wanted this to be a thread in which everyone could post their spring ideas. oh and oompadidoompity if i ever get a 3B i'm putting on a new barrel and leaving that one hell of a spring right where it is if thats a bad idea tell me so.

im gonna wait till i need petg and ask him if i can get a replacement bbb spring ie industrial with the stock spring its nothing to speacial only hits around 50 60 with the stock spring but they hit around 100+ with an industrial one

A nitefinder spring will work but it dosnt improve range drasticly
