So my onza has been a great bow for me so far really love the way it shoots, and etc. But i wanted to try and go with a half inch shorter draw just to see how it felt and if it could improve my accuracy a little. I understood how to adjust the mods on the nitro cams but i never adjusted it straight from the factory, it just felt good the way it was, so upon loosening the screw on my mod which apparently was way to tight cause i actually broke the end of my allen wrench off completley flush to the screw and have no "know how" to get the peice of my allen wrench out should i try to drill it out myself?, or leave it to the proffesionals?? why was it so tight to begin with?? i mean this thing must be cemented in lol.
