I gotta go with Barnacle Bill here. Do you have sail slides on the main? Or do you have a luff wire that fits in the mast groove?
But if you have to, I would go with the lazy jacks over the furler. I had in mast furling and didn't like it. It jammed too often. I like to be able to drop a sail.
In boom furling was an item in the seventies. You don't see those boats rigged with boom furlers anymore. I know because I used to own one - a Ranger 29. Today's boom furlers may be better but if you look at the shape of a sail, it is not a triangle and rolling it up like a shade doesn't work. The sail will need to fit the furler. In other words, the cart driving the horse.
Jib furlers and accepted as safe, reliable, and, if done properly, will not deter performance.
Personally, I like the Dutchman system more than lazy jacks but that's another argument (And has been on this forum).
