Well Eric, you stumped the dummy. I don't know what a stitch plate is, I don't know if the jacket does twist on the core, (thus the purchse of Thetueifelbergur Platinum) ever so slightly but in the length of the rope that ends up being the notable twist and does that accumulate to damage or stress the rope? I have notice the more supple ropes seem to twist the most beyond that I'm interested in knowing what the dynamics are and what is actually happening.
BTW, I do have my travel bag packed (probably forgot some needed hardware) I'm off to Paris so if you hear of some guy getting arrested climbing the Eiffel Tower............
Cheers
