Any barrel will work good, but between 14'' and 18'' is fine.
Bright fill, thick, hard to wipe, no dimples
Price a little heavy
I've shot many kinds of paint before, and none have had the neon-green fill I had with Steel. Very thick and juicy fill. Hard to bounce when hit by it, and doesn't curve alot. When you buy a case, request neon-green fill if you want to, because it's EXTREMELY hard to even wipe the fill. Though some WILL bounce, even on hard surfaces.
Buy it if you want to make sure someone was hit. Recommended for rec-play only, not hyperball, unless it's practice.
