Perfect Poser 

Is this the big easy line on the side facing the mountain? If so - this problem has great, slightly technical moves on good edges and jugs with lots of air. I don't know about the V2 grade, nor the R rating, since the landing is good and easy to pad/spot. This is probably the best downclimb off this boulder.

I think Perfect Poser is the Northeast corner, and it's tall. A fall from the top would hurt whatever you call it. Not sure about the best downclimb, but the easiest downclimb is the Northwest corner, V0 or less, slabby: to the right of the climber in the photo on this page. A number of variations exist, traverse left to right and back, etc. Super fun boulder.

Saw this being top roped on my last trip out to the Kraft Boulders. Looks like someone was nice enough to set up permanent gear on top. Still requires a pretty high free climb on the V0 side to set up, however. Use an attentive spotter while setting it up.

Start on the left side of the face and move towards the middle as you approach the top.

I say this is a V2+ as a highball or a V1-2 as a toprope. There are a couple technical moves with lots of exposure, which made me too scared to do this without a toprope. The landing is, however, nice and flat which makes it easy to protect with a spotter.

You can set up a toprope by climbing up the face to the right with a big ledge that has a half-pulled out bolt and then topping out with the jugs on the left. There is a worn single bolt top rope station at the top of the route.
