I' ve used Muzzy' s for more years than I care to remember. I' ve used the 100 gr
3 blade, 90 gr 4 blade (with wihich I took the ten point below), and am switching to the 100 gr 4 blade this year. I am partial to the 4 bladed heads as they, at least in my set-up, seem to fly better. Although I can' t remember any of them flying badly. I' ve always used 5" vanes also and I' m sure that has a lot to do with the good flight. I' m shooting the 100 gr 4 blade now on a GT XT 7595 at 28" and 421 gr at 280+ fps. They fly like a dart.
