I had a 58# Bamboo Longhunter that shot 2117's like a laser. Since you have found an arrow that shoots well off your particular bow, then you have found the simple solution to arrow selection, no matter what other options may be out there. It does not matter much beyond that. 2117's will put meat on the table, plain and simple. Consequently, your problem is essentially solved.
However, you will still, no doubt, want to dabble with other arrows as all archers are apt to do. That is fine - just remember that you don't need to get up tight trying to get the absolute most perfect performance in the universe. If you find something that outperforms your 2117's, fine, make the changeover. The point is the dabbling should be fun experimentation, not a vision quest. After all, you have found an excellent set up already.
The solution to bent arrows comes with experience. As you get better you will miss less frequently, and will destroy fewer arrows. When I got my first longbow from Dan Quillian, he advised me never to get too attached to my arrows, because they will not be around for very long. He was right.
