If you use all feet including the spots out left like you are in the pic, it is called Urbanator V3. If you only use feet and hand holds on the hanging shield of rock, no feet or hand out left it's called MegaMonster V5/6.
The line to the left is called Made in the Shade and is V3. The line you are on is Urbanator, if you traverse right you end up on Saddle Sore V4 which is a sit start scooted all the way in under the center scoop. If you traverse above the lip with your hands, it is no harder than V3 since the starting moves of Urbanator are the hardest, and the starting moves of Saddle Sore are the hardest and hence why each have the grade they do, but eh? As with any boulder, there is an infinite number of eliminates that can be done. What do I know though, I just scrubbed the moss and loose rock off of the face and made it climbable in the first place :P
I'm not going to argue with you about grades on the internet. I'm not sure what lip you're talking about but the route I was on, whatever it was is harder than V3, and I climb V7 so I feel as though I can make a fair judgement. It's likely some combination of the routes you've name dropped in your posts and in my opinion fell somewhere in the 4-5 range. Thanks for cleaning it, it's a cool piece of rock but please recognize that you can't say exactly what someone was doing from start to finish by looking at snapshot.
