Russell found a great extension when I half-bolted a basic uproute. Despite all the similar style variations I designed at Monster Rock, I just sunk the three bolts since I was sinking bolts elsewhere.
The grade might be soft 12a or possibly 11d, but the route it reminds me most of is the 12a Fear Insanity variation at Mrock. This one has a shorter easier approach, more moves through the crux (roughly four), but the moves are easier than Fear Insanity. On the other hand, Fear Insanity is a stout 5.12a, probably harder than Yertle.
