I have a 2011 hunter, set up at 70.1 pounds, 27.5" draw length. I am shooting a 398 grain injexion arrow at only 251 fps with a new set of vapor trail VTX strings/cables.
Before, I had the stock string/cables with the speed buttons. It was still slow then, but I was getting about 260 out of it. According to TAP I should get 266 fps out of it with no speed buttons.
My question is, do you think it is the speed studs causing the loss of speed? If so, which ones do you recommend, and hwo far from the axles/cams.
