I have heard the name of the strings, but that is about it. Strings are always a good option, and need to be replaced at least once a year, depending on how much you shoot and also a single cam is a lot harder on a string than a double. As far as changing everything else, are you sure you have that much room to cut your arrows? An inch is a lot of length. Stiffnes shouldnt be a problem because it will stiffen it. I wouldnt do it if you are forced to go to the mechanicals to get clearence after taking so much off your arrows. I also would not go to a mechanical for anything except turkeys. Also, the mechanicals with the wide cutting diameter were desighned for turkey hunting, not big game (with exceptions of course). Remember that you are going to get less penetration with a mechanical becuase of the energy to open the head, plus putting a wide head on will reduce penetration more. Also, the wider diameter puts more stress on the ppin that holds the blade on the head and if it hits something hard like a bone, who knows what will happen. It also wastes more energy with a wider blade if it hits at an angle and one blade opens a lot sooner than the others. I personally would stick with a good fixed blade. Why do you want to shorten your arrows and go to a mechanical anyway? I personally dont like them very much. Sorry for the late reply, I was out of town for a few days.
