I just figured those 3 would be enough to drive you nuts and keep you plenty busy. The best will show itself loud and clear. Here is a revised list.

BowTech
Matthews
Hoyt
Browning
PSE

If you have the time narrow 1 from each brand and then shoot all 5 of them back to back to make your final decision. I went with BowTechs binary cam systemto stay away from excessive tuning problems. One less thing to worry about. If you really want my opinion here is the best revision of the list:

BOWTECH!
