RE: Smoothest shooting recurve....or best in your opinion?
65 would be a nice weight to have if you live where you can hunt griz and moose, but 45-50 lbs is plenty for deer. Until my shoulders pooped out, my favorite draw weight was 55... mostly because I had been shooting ridiculously high poundage before, over 100 pounds. When you're used to shooting a 120 lbs longbow, a 55 lb recurve feels smooth as silk.[8D]
There are just too many great recurves out there for someone to point at only one and say 'that's the best.' A bow might be the best for a certain individual, but the guy standing right next to him might hate it. But as said above, your price range is killing your list of possibles. Plenty of bows on the used market in that price range, but new ones are few and far between.
If you want a new custom bow, then I think your best option is to go to Recurves.com and look under the 'one piece recurve' section at the ChekMate Falcon and Kings Pawn. Both are well within your price range, even fancied up a good bit. I've been shooting a Kings Pawn Special for about 5 years now and it's definitely a keeper. Still got quite a hankering to drop off into the takedown part of the site and order a Hunter II... just haven't yet been able to convince the household chief procurement officer of the great need.[8D]
