I'm getting a bimini on my Hunter 28.5 this week and want to add a sail tamer/handler to make stowing the main easier. I know of and have used lazy jacks which work well. There's a product called MackPack (www.macksails.com/mackpack) which combines a lazy jack system with a zippered mailsail cover. The MackPack is attached to the top of the boom below the mainsail and zips open along its top. Theoretically, you simply lower the main and the lazy jacks guide it neatly into the open cover on the boom. After some packing down of the slides, you just zip the cover closed. It looks quite practical and functional, yet simple. Anyone used one of know someone who has?
