I have had a bit of trouble with my Profurl, but all things considered I would not trade it for hank on sails.

Nice when cruising to approach a bridge, furl the sail most of the way, heave too on a scrap of jib, then put the rudder over, spin around, let the drum unwind, and sail under the bridge as it opens....

Also nice to USE the sail on those short stretches when you are motoring and the wind fills in.... something satisfying about grabbing that little bit of wind when and where you find it. (IMHO)
