But, if you have no tuning issues and are satisfied, it was a good move. One thing that I love about the binary or dual cams, is that I can shoot different arrrow and head combinations out to 35 yards without changing my sites, or rest.... for example, these are the combos that I can shoot....2512,2514,2315,2314, ics 340 or 400. Most all with heads 100-125 graiins. Pretty crazy.
