MAHLY 13, I don' t think your theory on how the rubber band will work is 100% correct.When I use 3 finger tips,and apply pressure evenly,all three blades roll back smooth, with little effort.They don' t " ketch" the rubber band until almost 100% open.For the most part, the blades stretch and roll the small rubber band,out and back.Now the o-ring,being that it is " stuck" in in it' s own grove in the broad head ferral,does' nt move one bit.The blades start to open,about an 1/4" ,then they have to " pinch cut" the o-ring to get to their full cutting dia......
Now,YES this works well,but I just thought the head " responded" much faster with the rubber band.YES, these rubber bands I' m talking about are the ones used with Rocket heads.
5 SHOT,,,Any easy way to test this set up to make sure the heads ARE staying closed on the launch.If I shoot through some sort of light paper,,maybe it would show ??,,what do you think ??[]
