[quote=MN3]I sail with a guy who has/had them
i have played with them and seen them when they wear down and need a re-build (i think it was over $100 for the rebuild)
they are awesome when they work but they can jam up (if you over sheet and have no more room to pull on the sheet for the internal mech to release)[/quote]
