I went to polesforyou.com (Vancouver WA) and they bent some poles for me. 0.34" Easton.
They have this circular plywood jig with a metal piece to hold one end of pole and then they bend it by hand around the circular jig.
They have several jigs with different radiuses.
They can bend it by hand, it springs part way back, then they can determine if it's bent enough, then bend it some more by hand as necesary.
