I use one of these new 8mm (they seem to be thinner than the spec) soft braided sheets which are also fairly slippery, so that it possibly does not have enough friction at the ratchet and makes me work harder than neccesary, I also feel that 10:1 on an A is overkill and I might try a second ratchet on top. I would also be keen to a sketch of the cascaded system. Thank you for the replies
