Hey Kevin,
I have 2 paddles. A Werner Powerhouse and a Werner Double Diamond. I use the powerhouse with my creekboat, and the double diamond for play boating. In my opinion the powerhouse is a bad choice for a play boating paddle. The blade is very big, and I love it for creeking. But I think if you were to use it repeatedly for play boating you'd end up damaging your shoulders.
If your mainly river running with some playboating on the side, maybe step down to the Sherpa which is a mid sized blade (The Powerhouse being a large size blade).
If you're doing a lot of play boating, maybe look at one of their larger play paddles.
Werner have a good interactive fit guide which can pick out a paddle for you, have a look:
