I bought a parker Challenger for my wife and she really likes it. the thing weighs about as much a a goose feather! It is very quite and she has not mentioned any jumping. If I did not have a new hoyt, I would have tried a parker out. The price seems to be good, and so far the quality is good. Hoyts are a damn good bow, but a little on the spendy side.
My wife bow is set at 50 pounds, so one set at 60 or 70 might be a little more of a hand full.
