I'm not going to run out and buy one, but you might take a look at this before you completely dismiss the concept:
Whitewater Inflatable Kayak K30X Incept Marine Ogden Utah
Click on the "watch Sally in action". I can't run that kind of water but he looks pretty confident in the boat.
I demo'd the Sally a year ago and thought it had merit, though it's a specialized tool and would probably be for someone who already had 3 boats. Sure is a lot easier hiking into someplace remote with it than a hardshell. Seemed like it could also be a lot more forgiving when you pitoned on a big drop. Also seemed like most of your pin situations could be quickly fixed with a prick of the knife, though the cockpit on the Sally was huge - not much pin potential that I could see. I was just too uncomfortable sitting in it for any length of time.
Once again, I'm not buying one but I didn't think the boat was garbage either.
