This is a good but stout climb for 11a. Perfect for getting in shape for similar overhung routes nearby. Climb more sloped holds and side pulls to the ledge for a rest. Try real hard to get higher, how do you even do it? Should I just pull through? Put off that thought til later, crank and get into cool stance under the final roof before the chains (might need a fingerlock to get you there). Pull the lip off a good hold, work the final couple feet until you can finally clip the chains! Phew 11a's are supposed to be easier than that.....
Just right of Crag Nazis', High First Bolt.
8ish bolts and chains. The first bolt is especially high, either get a long stick clip or be confident enough to not blow it. You might be able to stick clip from the short ledge 4 feet up.
