I think that, generally speaking, the longer bow would be more stable and/or forgiving for most shooters. That' s how it works out for me. BUT there' s a lot more to stability and forgiveness than just the axle length. I am shooting a 34" bow right now, and it shoots well. I do have to be a bit more careful about form with it, or I miss by more than I do with my old 43" bows. I also don' t see a huge advantage to shorter bows, but some guys do. Many people like the short bows, and like Buck Magnet. shoot them very well. It is fun to experiment with theories like this one. It' s just too bad it can cost so much. LOL
