Spares are indeed my favorite too, I always "st louis cut" them, and serve the rib section for dinner, and scrounge the meat off the remainder for freezing and use as an ingredient of impeccable goodness.
As I've mentioned elsewhere, with ribs I find myself going "medium" instead of low and slow, lately. The ribs I've done in an hour and a half often taste just as smokey, and are definately as tender/fall off the bone, as my low and slow versions.
Cold smoking some cheeses this weekend, and I DO mean cold smoking...hopefully it doesn't just freeze out there!
