Do you have specific models in mind? Are you talking clincher or tubular? What characteristics are you looking for (ride quality, durability, light weight)?
If you're looking for shorter distance (up to 1/2 IM) race tires, I'd suggest Veloflex Records. They don't have a super long life, but are much lighter than either Contis or Tufos and are FAST. They are a bit thin (19mm) so longer rides aren't going to be super comfortable, though.
