The guidebook (seems) to indicate you can rap Borderline at Squamish with 2 ropes - eventually using alternate anchors off the route.

Anyone have experience with this?

if you only want to do Borderline...I'd say you're better off climbing it to the Crest and then using it (the Crest) to escape into the North Gully and walk down. A single rope should be fine. Check the McClane guide for escaping off the Crest.

I'd think that the traversing on Borderline might make the descending tedious.

We climbed and rapped it on Sunday. The rap was actually very straightforward. P3 of Borderline required a small traverse at the end of the rap, but the ledge makes it easy. We then rapped to the terrace and did the standard terrace raps.

great, there you go then! : )

did you tag a rope for the rap? was the 11c pitch dry?

Climbed twins. I didn't do the 11c option on Borderline (should have though), but it looked bone dry to me. The entire climb was dry.
