I’ve been using 6mm perlon for a pull cord and it works pretty well. Still light and non-bulky, but with enough substance to pull “better”; and the ascenders I’ve been using seem to be able to grasp it when we need to really put some force on it.
The Beal stuff seems pretty good – stiff, a tad thick, and it comes in 120m spools so you can get 2-60m pieces from a spool.

We had at least 50′ of handline. The first descender had prussiks > ready to stop and changeover and climb back up. Plenty of experience from vertical caving world. Then would have re-rigged and rapped down a single rope, with the handline tied to the pulldown side of the rope. That’s one way. We actually did Mystery with a single 50m rope, using 60 meters of 3mm cord for the pulldown. That actually worked fine, except the cord stretches a lot and is hard to grip, being so thin. But it saved weight.

I have an Espirit 6mm “bone dry” personal alpine escape rope. I’d give it serious consideration for using all by its lonesome…burly piece of cord. And…comes with the middle premarked…
