Pretty well covered here. BK is gonna be the fastest, but doesn' t posess the letoff you seek Corb. My reccomendations fro the BowTech line would be the ExVFT and the 2004 Patriot singlecam. RB mentioned some other good manufacturers to try..Darton in particular.
P.S. Kevin Strother. VP of Engineering/Designer for BowTech has been posting here on the boards in the BowTech threads.
