Roller
furling would require a sail cut for that purpose, and will result in a less than ideal shape.
Sock''s are great until the wind picks up and makes pulling down the sock difficult without luffing the sail, and in high winds, when you need it the most, may not work at all.
Old racer trick that works great for cruising: Attach a belly
line. Put a reinforced patch in the center of the sail with a grommet in it. Before you raise the sail, put a light, say 1/4",
line through the patch and dead end with a figure eight. Leave the tail so that it will hang on the outside of the sail, then back to the lee rail to a block. Length will be determined by the size of the sail. You have to move it from side to side as you jibe, so a snatch block is best. When getting ready to douse, come up on the wind to luff the sail, trim the sheet snugly, pull in on the belly
line, and lower the sail. Most of the sail will now be on deck and managable. Stuff into your turtle (sail bag designed specifically for
spinnakers) and you are all set.
Not a bad way to do it. And you can easily handle it with two crew, and even one, if you are nimble enough.
