Thanks Matt and Nick - Let's say you are out on the wire in a blow. Will the carbo unit (2629) be easier on the arms in terms of holding the sheet and not cleating in, than the Hexa (194) block? Harken claims the carbo has 10:1 holding power @ 180 degree wrap. I haven't seen any claims for the 194, but it may just be a marketing ploy for the newer carbo blocks.
