My Excal Vortex "Right Stuff" package came with their new 150 gr Boltcutter broadheads. The Phoenix package I ordered a couple of years ago came with 100 gr Thunderheads. Excalibur claimed they now suggest the heavier 150 gr head for better long range (40-50 yrd) accuracy. I normally shoot under 30 yards but am curious about their claims. Anyone had any long range experience between the heavier and lighter heads. I would rather shoot a lighter head because there's more choices out there but I don't want to screw up the accuracy of the Vortex either. If I go with a lighter head should I look into a weighted insert?
