I use two different SRT setups for ascending. I will take pictures next time I set them up, or at least I'll try.
One setup is composed of a Sequoia SRT saddle. Croll ascender on my chest, with a prussik cord (i think it's technora), and a Pantin on my foot. The prussik serves as a backup to the Croll. This is my preferred SRT setup and it works well with Lava, Imori, and pretty much any rope you put it in.
Another setup is made up of a Sierra Moreno Ultralight. I use a Petzl Tibloc instead of a chest ascender, only because this saddle isn't really set up for SRT. I use the same prussik cord as that setup above, and the Pantin on my foot. With this saddle, I use HTP red rope- a 7/16" practically static line. Super great, and I'm sure that would work well with my Sequoia too, just haven't put those two together yet. Though this setup isn't perfect, with a few practice climbs, it's really pretty good.
