Gary E runs more scary shit than anyone I know. He soloed Bear creek at 600cfs, and was calling people to run Lake creek at 1600. I was shaking driving by it. If Gary peels out of an eddy and yells back, "go for it, you'll be fine" I worry about my sanity. "He's never wrong" if you don't mind running the shit, but I'm not sure he's right in the head. (imho he's one of the elite badasses)
That said, on the 15er you are probably okay. My earlier statement was more of a general creeking statement.
