I was really fortunate to be gifted a compound bow by a friend who can no longer use it. It's a 2009 Hoyt AlphaMax 32. It's set to a 27.5" draw length on an XTR #2 cam w/ XR-2D mods. After going to the archery store and getting measured, I'm a 28" draw length. So I need an XR-2E mod to get 28" DL. Question is, how hard is it to find these cam mods? This is my first time using a bow, and I'd like to get enough practice in to be effective by the open of deer season. So I certainly don't want to be waiting around months until I find the exact cam mod I need online. Another route is get an XTR #3 cam w/ XR-3A mod, but then I need to get it restrung (and even then - it would be difficult to find that combo). If it's not worth it, I might consider getting a used bow and transferring over the sights and all the other goodies, but I'd love to be able to use this bow if possible.
