I know you said Buzzz only, but I would try a Warship.. It's got glide for days and would rie out the anny without turning and burning.
The Pro D buzzz flips too easily when it is worn in, esp takes far too long to beat in, elite z will probably never get to that point of beat in, and the elite x takes too many chunks. Elite X would be my best guess if it weren't so susceptible to beating in. My Elite X buzzz had good sized pieces missing after less than a handful of rounds. Of course, I hit plenty of trees but I'd assume most disc golfers do.
