In general, Conti uses butyl tubes, so tufo sealant won't work (it is basically liquid latex, used to seal Tufo's unique latex sealed tubulars). I would suggest Stans, which one of my teammates uses in his conti tubulars with success (survived two potentially race-ending punctures due to the Stans).

Have no idea about the tape, but I've heard it makes install quick and easy and re-install a b!!ch. Glue is really not that hard to work with.

EDIT: back on topic... my choice for tubulars is Conti sprinters. Cheaper and more durable than other tubulars but still a race tire, and it grips in corners really well.
