I have to thank Tom for posting this. It was actually my question.
As far as static kernmantle, I will endorse the NO answer on a 2:3 Blake's hitch. I got stuck in a situation when my boss' boss rounded the corner and stopped for a chat. I would rather had talked on the ground but this black 8mm(?) stuff locked so hard I had to excuse myself, put on an ascender and rig out of that tail.
T-900 is not good. Works great for the double-dual lanyard keepers, but not for Fly.
The Fly is sufficiently static and I use it almost exclusively SRT. Going back to a more dynamic rig and DdRT is a lot more bouncy, which is more comfortable rec climbing.
I've just compiled a short list of ropes I can find and will buy lengths to make two hitches (I might like one of these) and also one of the pre-made ones -- red with black flecks.
I'm looking for some good performance in Kleimheist or VT systems. Each of the friction hitches cause the various ropes to perform differently. The comments in this thread are pretty well documented as to what hitches with what rope.
