RE: Smoothest shooting recurve....or best in your opinion?
My personal favorite is a Herters Pro hunter. Havent been able to get one since the 70s because the buisness closed in the early 80s. Ive got my original 1978 bow and found one on ebay the other day. In your price range, you might try Hoyts, persons, or martin. They all have pretty good bows. Ive had a few persons and Hoyts. Im still fishing with a Martin Mamba and an old Person.
My brother just bought a black widow. Very nice bow, but very expensive.
As for weight, dont go too heavy. You can kill a deer with 45lbs. My favorite bow is 58lbs but at my draw its 64lbs. I get pass throughs with it rather easy.
