Some will definitely say YES, it makes a difference. Some would never know. Let's see now, we've got 11", 13", 15", & 17" handles, so what difference does it make, if we hit somewhere in between one of those ............ ?
Don't forget the 9" handles on the original Rev 1's. I know of a great flyer that had a set of 14"s made up. It might be a case of what you get used to.
