I like the Pro-furl because it does not change the existing rig at all , if it breaks you could pull it down and pitch it over the side, if you were so inclined , hank on a sail & keep going .
I had problems with 2 Hood units on other boats and wouldn't buy one at any price over $10 , I do like Hood sails , got a Hood main .
I work closely with some riggers and sailmakers and all of them say they dont know if Pro-Furl is any good because they have never had to repair or replace one they installed , they could be crap but they wont break so we can find out . Also that is what all of them use on their own boats .
