The only difference I've seen (other than noise and drop) is if I really goof up--super bad release, short draw, etc--the high backs seem to stabilize quicker. I don't make a goof that bad very often though. I have my arrows matched closely enough to my bow that I can shoot at least 20 yds (as long as I do my part correctly) with no fletching at all. At that distance, the feathers are just there tocompensate formy mistakes, or in the case of a broadhead to keep the broadhead from steering the arrow.
