on the viper 830 with a 95 sqm kite we used 57mm Harken ratchet as the back turning block (~180 degree turn) and a 57 mm Ratchamatic forward for the ~ 90 degree turn. Great holding power but would sometimes use a primary as a snubber on a reach. In light air we would just turn off the back ratchet to make it possible to pay out the kite sheet and to be able to let the sheet run for gybes. Nothing magic really
