Maybe this will help, Annie did it once in her playboat and she is coming back for a rematch in her Mamba. When I ran it in high water last fall, we left in the morning thinking we were going for a play run on the Fish, but the Fish flooded to a 30 year high and so we changed at the last minute and took playboats or river running playboats down the St. Regis. We had an experienced group and there were three swims as I recall. There are no play spots but there may be some glassy big waves to "catch on the fly." I'm taking the Nomad because, like Christian, I will be paddling that boat at HOHW next weekend. But if you are fine on the Main Channel of the Ottawa in your RAD, there's nothing like McCoy's, Butcher's Knife, Norman's or Coli on the St. Regis. The difference is there lake size pools between the drops on the Ottawa. On the St. Regis you put on in whitewater and all you see downstream is whitewater and you pick your way down and you take a break when you need one in an eddy. Its that continuous. Sandra did it in her small boat as I recall.
