RE: Sighting in????
I personally only had problems with hoyts. The ones that were like a spear head with the side blades recessed. Those flew high on me so I quit using them. I shoot muzzy's and thunder heads and have had no noticable difference. I would atleast shoot one broad head to be sure. I've read posts on this board that says you may have to change weight a litlle to get the same flight.
Good luck.
