Tell you what, I shoot a 26" draw which is really short compared to many people. I shot alot of bows before I decided to buy the Parker UL 31. Their modules are pretty nifty. One of the more indepth comparisons that i made when trying to choose was between the Buckmasters G2 and the UL 31.

Speed wise, using the same exact setups (rest, arrow, etc.), the Buckmaster was about 5 fps slower than the UL 31. The Parker just felt better to me (but that is just me. I' m sure there are some that will disagree)

IMHO, Parker produces a quality product backed by what many people consider quality customer service. I don' t think you could go wrong with the Parker Challenger.

The UL 31 also comes in a 60# draw weight ajustable down to 50#, if you can swing the price.
