Rowed it last week at about 2200, 14' fishing frame raft, big waves below needle's eye, but Right side is runnable at entrance so it is easier than at low water when you have to run the needle river left. Water level gives you more options at the bottom of the needle, but be prepared to pull away from the wall on river right as the river turns left at the end of that rapid. Red Canyon was fine, bigger waves, fewer rocks. I found it easier than at lower levels. That said, I'd follow all the rules, instruction, well-fitted pfds, etc.
