Consider the Dutchman
My H-28 came with a Dutchman Flaking System, and in my experience, it beats lazy jacks, hands down. The installation is more difficult, but the system is vastly superior to lazy jacks. In practice, two sets of grommets, placed one under the other and several feet apart, are sewn into the main. Two lengths of very heavy monofiliment are led vertically from the topping lift to the boom. The rig presents very little windage or weight aloft, and the sail flakes itself on top of the boom when lowered. The only problem is that due to UV degradation, you have to replace the monofiliment about every two years. Takes about half an hour with a helper. You should be able to find them on the web.
