All I have ever shot is the Muzzy 3 blade 100gr.. I switched from 4in vanes to blazers and my groups tightened a lot! Then I put a 3 degree Helix on my blazers and have the tightest group I have ever shot.. (Not that I would ever take the shot, but I am sighted in at 50 yards, 4 arrows in a 1in circle with the broadheads!)
