Jonathan rated NRGHB hardish 5.11 and it felt that way to me, way back. I'm guessing it is a good 5.9 by not cutting left. It is always interesting to see how others interpret beta. The nine plus way looks good too.
About the bolting. I do know this route was vandalized by The Man From S.C.A.R.E. I think the 1/2" Rawl, first bolt, is the fix for what was taken. The other three bolts all look like the work of the Plastic Prince. He loved overhangs and was not one to put in contrived runouts!
