got it, put it on, shot it with my winter jacket on. ************string didn't touch my jacket, which it normally would have torn a hole in it.*********** that in and of itself makes it completely worth it. besides that the only thing i hear is my drop zone launcher arm landing. can't feel a thing and i shoot off the riser. it made a definite difference. backed up to 70 yds. good thing i was aiming in the center of the target. i hit high. had to put my slide on 67 yards so i definately picked up a couple fps. i shoot 388 grains. shot a nice group from 70 in a breeze. i remember seeing somewhere how to quiet the dz arm and now that that is all i hear at all i'm going to find it. i like it. the bolt takes a bigger allen wrench than anything a bow uses, which i don't have. i had to use pliers and it would be nice if it took the same size as a limb bolt. so far sooo greeeeaaaat. thanks. john
