Very long for such a moderate route. There is a fun move over a short overhanging section at the very top. The bolt line zig zags a bit so rope drag gets heinous. It would probably be helpful to use a couple of long slings in the middle. I can see why it was bolted this way because the left-most bolts force you out onto the edge of the arete where it is exciting if you look down.

A lot of bolts, maybe 14 or 15. You probably want to use a 70M rope. Watch the end when lowering if using a 60. You would probably have to walk up the slope to lower with a 60 meter rope.
