Pinnacle to PDale is my most-run river, and I would disagree with Dave above just a little bit.
I think at these flows the easier line in Spikebuck is to stay right of center and move to the left. If your'e comfortable making that move, you'll be fine. Right isn't a bad choice, but it's not the easiest, especially if you get too far right, or you're not real comfortable amongst a bunch of small rocks.
These are great flows for this run: forgivingly deep if you flip, not pushy, easy to scout everything.
At three rocks, the easy line is right, but scout as indicated above.
THere are a couple of surf spots in there if you're in a smaller boat. Have a good time. Great run for III boaters. I go back to it often (except this year for some reason)
"self-aggrandizing jackass" - it says it right on the label
