I guess I'd qualify as a "Hoyt haver", lol. I had the AM32 as my go-to rig this past season. I've shot all of this years Hoyt models as well. With "cost" not being a factor, I ultimately chose the Maxxis31 for 2010.
The Alphaburner is a fine bow, but having the chance to shoot the Alphaburner and Maxxis side-by-side, I chose the Maxxis. The AB was just a bit more aggressive than I prefer—as I am mainly interested in a good, comfortable hunting bow. I relaxed a bit too much the first time I came to full draw with the AB, and as previously mentioned, it tried to "run". For guys who've shot "speed bows" previously, and/or particularly shot Spirals, it's probably a non-issue.
As far as bows pushing 340+, I will say the Alphaburner was one of the more comfortable I've personally shot. The Alphaburner and the SR-71 were tops for me, but to be fair, there are a few 340+ bows I haven't had a chance to shoot this year.
Anyway, per your "list", I'd personally rank them: Maxxis, AlphaMax, AlphaBurner. :thumbs_up
