Can't speak for the Hood System but
I have a Profurl and love it. My experience says that it is the furler choice of coastal and long distance cruisers, because you install it and forget it. the bearings are sealed and I only know of one person who ever replaced any part of one, and that was because a Mexican boatyard buckled his older, and no longer used head-foil when they were dropping his mast. It was only the head-foil he had to replace.Joe
