I was with Matt last week and was rowing a 15'er. Left was a relatively easy line, you had to pull right at the bottom, but wasn't difficult. We watched two duckies in the group in front of us run it. One made it right, the other went right over the rock/pourover on the left. Took a while, but they were able to paddle out of it and not flip. Guessing it is a rock now and not a pourover.
I had been told by a commercial guide that the right side eddy had been blown out and we would have to eddy left (from a report at higher water). That was not true. We were able to eddy out on the right and it was a fairly short and easy scout. The water above the rapid is a slow moving pool, so there is plenty of time to get left.
The tree was what really bothered me. Couldn't see it from above, but could from the scout. It was really bouncing around in there. It is parallel to the current but the left line pushes you even more left away from it (had to ship the left oar going through), so was pretty much out of play, but of course that could change or someone could botch their line.
FYI - Tappan II no longer exists.
Another thing to note -
Lake Creek is a big hit and unavoidable. Good idea to scout as you have to turn your boat left to line up for it after hitting a couple straight. It held me for about 5 seconds and I was rowing a heavy boat.
Let me know if you have any other questions.
