I feel like I ran Super colider for the first time (I've only run it a couple of times) was around this level. I felt like the entry was a little tricky...you need to be close the rock on river left, but not too close or you could get spun and find yourself in the hole - that type of thing. I had to roll, but thankfully I already cleared the hole so it worked out ok.
From what I remember (I haven't run it this year), White line was very manageable at this level. The guy that was in front of me got stuck in the hole and I pushed him out as I came through, but then I didn't get stuck in the hole, so it probably wasn't super sticky.
Again, I've only run it a few times - sorry this info isn't very technical.
I am hoping to get up there on Tues if you want to meet up. If no one else is free to run uppers, we could do lowers laps. It would have to be morning/early afternoon for me.
