a rap with a 60 is pretty sketchy, even when rapping uphill. Might be better off with a 70 or walking off, or continuing up to summit. Pulling the roof is a fun move--twin cracks provide great hand placements. Gets a little wide and steep then eases up a bit.
Not sure if a 60 will reach on a rap, a 70 may be needed. Sweet crack climbing and luckily the initial roof isn't bad so you can warmup a little before it is strenuous. Cams to #4 will be good with emphasis on .5-2 inch.
