I too have shot Thunderheads for many years. This year I got a hold of some of those Montec G5' s. I tested them for myself and found they flew better and penetrated deeper. Possibly because of the cut on contact point. Not sure but believe the thicker blades will hold up better if bone is accidently hit. (Don' t want to go into the bone braker thing after the other recent thread.) And yup, they look way cool! []
