I've been impressed about what I've read so far on the JSD. Most of what I like has already been discussed above. I find the data compelling. Lots of good info here: Jordan Series Drogue
For getting off a lee shore I think a true storm jib and tri sail arrangement and taking the seas 50 or so degrees of the bow will be my first choice (when I'm eventually confronted with those conditions). An anchor or drogue will slow you down, but it won't stop progress to the lee. You'd better have some gear to be able to make sufficient headway to weather. I think I'll be buying a JSD, but after two years of looking, I feel like I'm still doing my homework. Opinions on storm tactics, both professional and amateur, are as varied as the boats/skippers that use them.
