Also, do ya'll tie into the rope with your cow's tale every 10-20 feet? I've read about it, but never actually met anyone who does. Seems like a terribly inefficient thing to do. I've thought about pushing a prusik along above my top ascender. Any thoughts on that?
Thanks

I have never seen a croll with an biner between the ascender and the D-link.
I would attach the croll directly to the D-link. That is how it is designed to work.

If the chest harness webbing is threaded directly though the Croll, I don't see how that would be nylon-on-nylon contact. You should be fine.

I think most people would agree that once your weight is on the rope, the force of gravity tends to keep the top of the croll and the rope from making much contact. Besides, as has been pointed out already, the chest harness is not life supporting.

A few years ago when I made my frogging system I had a "screamer" attached to the short cow's tail via a screw link with a locking biner on the other end. I used tape to keep everything lined up on the major axis. My thought was that the screamer would give me the dynamic-ness necessary to absorb a fall. I don't know how well that would work, but I'm glad I never tested it with a fall.
