As far as I know, they make very good racquets, but their thing is much more about fitting individual players with racquets that optimize their strokes. Pretty sure they use video clips and some computer analysis to check swing speed, etc.
A friend of mine went to one of the big tennis operations in Florida a couple years ago with a group and they got to meet "the Bosworth people" for a talk and some demos one morning. They analyzed her shots, had her try a couple of their racquets, and she was pleasantly surprised with the "comfortable fit" they got for her in rather short order. She just wasn't ready to plunk down the cabbage for one or two of their custom racquets on the spot.
So long-story-long, decent racquets from Bosworth, but you might be sort of rolling the dice with buying one that hasn't been matched up with your game. I suppose that's the case with any unfamiliar racquet we might snag for ourselves, but I've certainly gone the buy-it-to-try-it route myself... and I'll do it again!
