I'm shooting a 58in bow and considering moving up to 64in. I seem to be able to pull a higher draw weight more smoothly with the longer bow. I'll continue testing this theory at the WV expo at the end of the month. Love my current bow, but at the very least I'm finding a psychological difference with a longer bow. Also, everything I have read from the Bowyers Bible vol 3 (so far) suggests people used shorter bows for specific purposes. Example; shooting from horseback. As always, I think it all goes back to personal opinion and what feels good to you. Just my 2 cents.......Charlie
