I did enjoy Grim-Ace's first pitch, good face climbing. And I did sling the block. I used a regular length single sling and MAYBE it would have held. It was around a nubbin that kept it in place. I didn't like it.
I had a triple sling on my harness but it didn't seem you could run a sling all the way around, it is hard to describe. I may have just messed up.
If you are comfy running it out a bit in 5.7 territory then the next move gets you bomber pro.
