I would just cut them at 380%
the trigger should handle it no problem.

I'll have to keep that in mind i guess the next time i re-rig. I'm going to shoot it this way for a bit until i decide to upgrade the trigger mech... which is a ways down the road. I'm using the mean-green bands from neptonics. they have 380% stretch but i think it puts a lot of load on the gun and i'm not sure if the sears on the gun will handle it. I did 320 to be on the safe side but if feels a tad soft. i was thinking of going to 340% next.

I think it would shoot a lot better using the new sigalsub 14.5mm rubbers at 400% from everything my friends have been telling me. I'm actually picking up a bunch of it to rerig some of my guns the next time I see petros haha.

Do you think 16mm 320% band stretch is too weak for a 100cm? its the Picasso magnum rail if that helps. i finally got 2 bands on my gun is why im asking.
