M_Boats: Reefing M17s

All this talk about slugs and slots got me to thinking about reefing. I have one reef point some 3 feet up, but I am wondering if anyone has found the need for a second or third. Does a furling headsail do the trick for reducing area up forward? Has anyone tried a jiffy reefing setup like the pricey Harken kit in the West Marine catalog? Looks workable to me, but I am only familiar with a cam cleat on the boom and a hook at the gooseneck, and lots of working room. Thanks, Tom Jenkins Scintilla
