I think Foxton will be fine. I've seen him run big class IV back in the midwest and roll up mid-currents. He's also creeked class IV before and has a VERY solid brace. Like I said, he hits his roll 50/50, but he hasn't boated in a while and wants something to whet his whistle. He's only out for a couple of weeks and wants to taste some real CO boating.
Also, we are *probably* going Saturday a.m. but no one we are going with knows the lines. One boater is extremely experienced, then I'm more in the middle and my buddy is on the low end of intermediate with a touch of beginner. So, we have a good, colorful crew, and I think we can find the lines easily enough.
