If i was you i would run straight 100ll for the first ride back out. Just for cheap ensurance. And see where that takes you. 7psi at 3000' on 50/50 av might be pushin it?
I agree with 50/50 with av mixed is def pushing it. Boondocker told me if I was going to run 7lbs I should be at a 70% of 112 race and 30% pump to be safe. I am riding at a lower elevation (1600- 3500). But I have to think at your elevation you should be at least 50 / 50 with 112 race not av to stay on the safe side. Just what I have read and herd.. I am no expert.
