Once put a dynamometer on our set of fiddle blocks I was surprised at the losses ~20% with the supplied double braid. Always wanted to try a static kermantle rope, much like the Sterling, to see if it improved efficiency. Size of the pulleys is of course a factor as well, these seem to be a little more compact than the traditional fiddle blocks.
