i am a big fan of roller furling
i believe all the "around alone" boats that finished used profurl.
that is what i use.
so far we have been in 4 gales, 1 storm, and through hurricane michelle (at anchor
) in bermuda. our boat and sails have had no problems or signs of wear.
if you look at http://kimberlite1.homestead.com you will see a video of us running downwind in 30+ knots of wind with just very small furled genoa.
