I've been using 5" helical feathers on my hunting arrows for max stabilization. At 20yds. no prob, but as my distance increases I definitely notice the drag affecting my trajectory. I've heard alot about the Quickspins and their site says a 4" QS fletched at a slight offset (less drag and more rest clearance than helical) would rival a 5" helical fletch feather. Can anyone vouch for this to be true? THANX!
