Just got a killer deal on a Boom Vang. Want to know what type of attachment points should I get? Like the boom should I just get a one bolt boom bail and what size? Also the mast, should I get something that will move to both sides or a mast hound. It is a soft Vang. Don't want to spend a lot but would like something descent, is that possible? I will be installing this myself. Thank You for the input. Dick
