Take the above advice very seriously. I'm a big a speed freak as anyone, and I have fun shooting fast bows, but if ultimate accuracy is your goal I would opt for a milder set up. The speed you might give up will only be noticed on a chronograph. I have a BK2, and have shot a Black Max on many occasions and they have a way of convincing you that shooting shooting short brace height bows is easy. Sometimes I'm shooting nocks off at 30 yards consistently at 350+ fps but the next day I'm lucky to have pie plate size groups. Everything about your form as to be perfectly consistent from shot to shot and day to day and even then even the best shots (a group into which I do not fall) will get fliers.

All the speed you could ever need can be had in forgiving, plesant to shoot configurations from several manuf. Of the ones you've mentioned I would say look at the Liberty by Bowtech or the Outback by Mathews. I've shot both and they are smooth, recoil free, quiet and forgiving to shoot. There are several other manuf who make bows that will fall into this category as well. I would shoot several and prioritize smoothness, noise level, and overall comfort of shooting over speed. For me the bow that fit that bill was the Bowtech Liberty.

But, I still love to pull out the BK2 and sling a few downrange at 350+ fps every now and then.
