Speed is of secondary importance. As PAB noted, other specifications take precedence. Of course, human whim lends some bias as does the desire to try something different. If I can shoot acceptably with the bow (which determines whether the bow is sold or not), then a chrony's opinion is sought. I don't think speed put any more deer on mt table this past year (shooting BK2) than the slower bows of previous years. Confidence in my abilities and my equipment plays a far larger role. I still get as close as I can - most times I stillhunt or spot & stalk.
Now I'm in the stickbow experimentation phase and speed is nowhere near the BK2 but the fun is the same - just a very steep learning curve!
