The max limit is a rough guess. If you have good beta on runnable levels, please add a comment.
The last hurrah before things calm down for the rest of the trip, High Falls is a drop of about 5 feet. The conservative choice is to run left of a small rocky island (which may disappear at high water) for a boof into a hole that doesn't seem to be sticky at moderate levels. The other choice is to run the very far right, avoiding the rocks that you want to be very close to, while still missing the hole a couple of feet further out. Scouting and setting safety are easily done from the right side.
