I thought there was another thread for this stuff but couldn't find it.
This is my SRT rig. It consists of a Petzl Minitraxion which I attatch to my harness's sliding D, and a Petzl Tibloc which is connected to a screw-locking biner and footloop.
Once you're standing next to the line and clipped in, you just put your foot in the loop and "stand up", the rope slides through the minitraxion to the extent of your push, then you "sit down" and grab the rope underneat the Tibloc, and slide it up the rope till it hits the bottom of the minitraxion and then you "stand up" again. Fairly simple rig, I can ascend 150 feet in about 4 or 5 mins, without much effort. It's just sitting down and standing up, you don't need to hold your own weight or strain at all.
To descend using this system, I pull a bight of rope up between the two, loop it through a 'figure 8 descender'. Clipping the footloop above or below the minitraxion allows me to add or subtract the components from the system.
I've been using this for a while now, it's comfy and I'm quick with it. The minitraxion has a sliding cheek, so you can add it anywhere, and the Tibloc just slips onto the rope.
