RE: question
My very first bowfishing bow was a PSE Impala. I thought the handle was a bit too big and bulky, but I do remember it sat nice in the hand. It was just a little uncomfortable fighting fish in because of the bigger grip. It's got the threaded-inserts for accessories, including the stabilizer bushing. I've never shot the Kingfisher.
I would say 50-pounds only because you can short-draw close shots, and still have the power for longer and deeper shots.
