One can see bolts and rivets along the crack. This route could have been A3 or A4 and a very proud line... However there were many rivets on this pitch where it would be possible to place gear. Like a rivet next to a bomber #6 placement. Other than this it has some fun thin stuff to deal with.
Has this line been climbed free? A couple of years ago ABS and I ran it on a top rope, and while we did not do it free at the time, there seemed to be a reasonable sequence that could go free if you have the finger strength and the reach. Might make an excellent hard climb for the 5.14 generation.
