Definitley start up absent friend (to the left), makes it a miles better route in my opinion (and it's already awesome). Good bouldery start to good gear and shake out, nip out to the threads, and go for glory up the arete. Makes the last move pretty wild, you can't see your belayer or any gear, just your rope snaking away into oblivion. Awesome. Still E5 mind, I know it was generally considered soft for the grade with the original start, so this probably just makes it proper E5.
Absent friend is well worth doing to. Pretty hard, but very safe. Maybe 7a+? and when you've done that...
Crisis Zone. Simply stunning. I think Endless flight left hand start and crisis zone are the 2 best "craggy" routes i've done. Better than anything on the grit (that I've done I mean), and surely the best routes in the county
