I went to 4 fletch about a month ago. I do like the flight a little better,and it does hid a minor bad release. I am shooting the steelforce broadhead and everything is good with that. I really dought you will see much between 3 or 4 fletch. I saw a minor one, and that is because my release isn' t the smoothest at times. I did mine in 4" 90 degree. one good thing is I don' t need to knock arrow any certain way.
