This is the leftmost route of the trio of tens on the primo wall. The well featured route is surprisingly pumpy with predominantly slopers for handholds, yet plenty of options for feet. The route is well protected which makes it a good first lead for the 10/11- aspiring leader, as well as a good warmup for the real business that the primo wall has to offer.
There is no way this route is 10a by even the severest grading standard. It's probably harder than many 11a routes in Clear Creek and Boulder Canyon. So, give it 10c at least.
Good job.... I don't like to grade routes until others climb it and we can make a consenses... thanks, I felt it 5.10c myself but not any harder at all.
I'd go with 5.10c as well, with the caveat for the 5.10 climber that there is a very in-obvious and sneaky move to the left just about the time things start to feel dicey. What looks like straight up, ain't. This was probably at the third bolt.
This route if taken directly (no deviation left at 3rd bolt) feels like 11a/b, sans a tough sloper sequence. Yet moving left at 3rd bolt makes it 10+ in my opinion.
