I would suggest one of the long playboats that are currently being marketed at river running playboat. The Liquid Logic CR125 and the Dagger RX y are much more playboat than river run, but are still easy to handle down river.
I have a Liquid Logic CR 125 and at 180 lb, I can flatwater cartwheel it. The extra length (a whopping 4 inches) really slow things down well (not the hull, but you can react a lot slower and get away with it). I am getting medium speed, controlled cartwheels in the hole and on an eddy line.
I picked up the boat to run stuff like Clear Creek; fun cartwheel hole at the top, then continues class 4 fun all the way to the take out. It really is a do anything go anywhere boat, and I am enjoying the entire river (not just the hole anymore).
The Liquid Logic 125 is for sale if you're interested (budget is stretched a bit thin lately) and could let it go for $550 if you're interested. Have a skirt also.
Let me know,
