Because of the way recurves open at full draw, the limb tips aren't pulled together as much as on a straight longbow, thus the string angle is less acute. In practice, this means that folks can shoot a recurve anywhere from two to four inches shorter than a straight longbow before noticing a difference. A highly r/d hybrid would usually fall somewhere in the middle. Bow weight also affects one's perception of finger pinch. For example, on the same length bow, a 60# bow puts more pressure on the fingers than a 45# bow. The string might be creating quite a bit of pinch, but you might not notice it at, certainly not as muchl, at the lower draw weight.
Personally, I think a 62-inch recurve is about right for a 29 plus inch draw, even a 64-inch recurve.
I have a 28-inch draw. I start to notice finger pinch on a 60-inch mild r/d longbow, a 56-inch recurve, and a 64-inch straight longbow. I can shoot bows shorter than this, but I usually don't. Right now, my straight bows are 66 inches, mild r/d bows are 64 inches and recurves are 60 inches, with one 60-inch mild r/d longbow.
