I have a 62" that is 55# @ 28". It is quiet and shoots well, but it is kind of a thumper (hand shock). Kent's bows are all designed for B50 dacron only, unless he has made a change of late. Since mine is an old one (no warranty issues), I made up an 8 strand D97, padded the loops to 16 strands with B50, then added yarn serving. The hand shock totally disappeared, but all the good qualities of the bow remained. I don't shoot it often, though, because I tend to like shorter bows.
The quality of his bows is high. They are not screaming fast. Mine was shocky, but that may not be the case with all of them. Your tolerance for hand shock may be different too, but it hurt my elbow to shoot it very much.
