Lock Jack and wott rope?

[duff]

Passing along a question I can't answer from a climber friend in Australia:

Does anyone climb on a Lock Jack, and if you do, what's a great rope combination that doesn't slip (even on occasion)?

Ropes tried :
Samson: Arbormaster, Bluestreak
Yale: XTC
New England: HiVee and the Fly

Thanx

It was origonaly designed for use with XTC, from what I hear. You can get other cams for smaller ropes, even Fly.
