All I got to say is 4 blades, with over 4" total cutting area compared to two blades. A logical person cannot argue with these facts. I can't say I have ever had a trailing problem with 3 blade thunderheads, 3 blade muzzys, 4 blade slick tricks, or 2 bladed magnus for that matter. Some people just consistently hit high, and that I notice is the usual issue here.
