yhea. I''ve got enough roach right now with my partialy battened main that I catch the topping lift, but not the backstay with my sail, but the sail slips by, and then fills up on the other side after a second. I was afraid it wouldnt do that with a full batten system. I''m ok with using the halyard, or hell, even tying off to the backstay for a topping lift. one less line on the boat is one less thing to break or get in the way.
so... price aside, what are the disadvantages of a solid vang?
