Check with others.....as I recall from the depths of a snowy winter afternoon... before you raise the spin, sheet in HARD on the mainsheet and cleat it, as the mainsheet acts as a backstay, and will prevent the mast and comptip from snapping. So once the main is locked, raise the spin, play the sheet, and you are good to go.
Better if you have experienced crew, however it is possible that a competant single hander could manage it. Those in our catamaran fleet who fly spinakers always use crew.
Sure, roller furling is always easier, but snuffers work amazingly well, with about the same effort. Don't forget the McLube....
