Don't know your physical stature, but if you are having some shoulder problems, I wouldn't go much over 50# that's for sure. Over-bowing will definitely not do that shoulder any good.

Lots of good recurves out there for less than $500. I haven't shot the Chek-Mate Falcon one-piece recurve, but suspect it would provide a smooth draw and some very nice shooting at a 60-64" length, and a great way to get started for around $200. I have a CM T/D recurve that was only $350. I like T/D's as they have more riser mass, less hand shock, and easier to hit what you're pointing at, in my opinion. I think the new Martins are way over-priced, again that's my opinion. Heck, for that matter shoot that Browning for awhile, get some arrows flying good, find out if you can shoot well at 45# comfortably. In the meantime go to local shoots/pro-shops, check out different recurves others are shooting.
