I would consider myself a solid III boater, with the ability to do IV when I'm on, and/or pumped.
This is the first year I've done Waterton, and did it twice. Once at like 450, and once at 1100-1200.
I wouldn't consider myself a playboater by any means, but my buddy can throw around a bit. At low water he had trouble getting into the river wide hole to surf. And He didn't really see opportunity for other play.
Now at 1200 for us it was class IV, with no sign of play. But it was our fist time at that level.
I think it comes down to where your comfort level is. Neither of us are big creekers or big playboaters, we're working on both.
I could see if you were used to V's how Waterton would be sweet butter for getting thrown around in a playboat.
But if you're an average boater (III-IV) you might not consider it a play run.
I've done Bridges so many times, I think I could do it blindfolded and backwards, so for me Bridges at high water is a great play run. However I've been with people who have seen God on my so called "play run". So it all comes down to your perspective.
You ARE a soul, you HAVE a body.
