I just tried re-banding a gun with the Acid Green band from Neptonics following the formula for 380% stretch. I tried pulling the band back to the shark fin tab to see what it will be like in the water and I heard/ felt a tear between my sternum and rib before I made it. Not hurting right now but I expect some soreness tomorrow. Do you add a couple of inches to account for the width of the band slot and the waste beyond the constrictor knot? I assumed that would be made up in the wishbones. I'm hoping that pre-stretching will make this length usable but that made me feel like I need to turn my man card in for resignation.
