With your draw length, I'd recommend a 64- or 62-inch recurve, preferably the 64-inch. That limits your choices in a newer/contemporary Bear to a Super Kodiak or a Bear TD with a B riser and no.3 limbs. Maybe the new K-4 is also made in that length. There are some older Bear models that were offered in 64-inch and longer lengths as well.
If you're measuring your draw length on a compound, it will likely decrease an inch or two when you switch to trad equipment. That means you could go with something about 2 inches shorter than what I'm recommending.
Certainly can shoot a shorter recurve, and I'm sure others with long draws will attest to that, but the bow is much more likely to stack, and finger pinch will increase, whether you perceive it or not.
On a 50# recurve, the weight will likely increase from 2# to 3# per inch of draw over 28 inches, i.e., 6# to 9# heavier than the weight marked at 28 inches. Thus, you would want a bow marked about 42#-44#@28 inches to achieve 50# at a 31-inch draw length. Not exact, but pretty close.
Good luck on your search.
