I've never run a furling equipped jib before, and had two questions: can it be used to decrease jib surface area (easy reefing) in higher wind conditions? And, is there any reason to rig the jib as shown in the manual: with the standing end of the jibsheet tied to the block, passed through the grommet in the clew of the sail and routed back through the jib block (as opposed to simply tying the jibsheet to the clew directly?
