With the Tornado style system (same as Nacra infusion and Hobie Tiger) you can easily make the downhaul endless so you never run out of rope and its also easy to adjust the pre-tension on the system to take any slack out of the system depending on the wind strength.

Endless Jib sheets and rotation are really cool, even if you leave the leeward side uncleated you can simply pull the windward tail and cleat the leeward side.
