Earlier on today, I made up a bandset from Burning Skull Brand .55 elastic (naturally tougher and stronger than GZK and Alsopp .55), with a taper of 15-20mm, aiming to shoot 8mm steel from it. I took a few brief shots, and the power/performance seems absolutely amazing. The trajectory was very flat, too. I'll do some more thorough tests tomorrow and report back, but my first impression was a great one! Have any of you got much experience with BSB? If so, were you satisfied?
