The profile of the bow can make a difference too. You can generally get away with a couple inches shorter with a stringfollow bow, and not lose any smoothness or forgiveness compared to a longer straight or reflex profile. I have a 26 1/2" draw, and so far one of my most accurate bows is a 68" Miller Old Tom. My 66" bows shoot very well at my draw also, but are not as forgiving of my release errors. The exception is my 66" stringfollow Pete George which is my other most accurate bow. While it's shorter it is just as forgiving as the longer bow. Can't wait for my Sunset Hill stringfollows to arrive - should be saaweet as well! Oh yeah, the grip can be just as important with forgiveness as length, if not more, so make sure you have it sized to your hand especially with the straight or dished styles.
