I have the same spin sheet system as Jake and it works well on a Hobie Tiger. When it is really blowing the sheet is only just long enough and the bungee really gets stretched out, but it is just a case of getting used to less slack on the lazy sheet.

One problem with having the sheet this short - you can't rig a doubler system for distance racing. I just bought a separate (longer) sheet to handle this. A little more clutter on deck is tolerable on a 100 mile spinnaker run.
