These guys have come out with some really nice ropes this past year and worth checking out.

...I wouldn't hesitate to try out some of their products.
Ah, I know the Tri Tech is expensive because its the first cut resistant rope that doesn't use a wire core, so I suspect the fibers that make it up are pretty hefty price wise. Sounds like the Tech 11 is somewhat similar, so that would be my guess as to their high cost.
Sterling's HTP static 10mm is the ultimate SRT accss line, imo.
