As has already been said, c9 gave a pretty good range above: (8B)4.
The problem is that razz isn't just about the first three cards - it's not like hold 'em where you can commit to a hand like AT because at least it'll always have some showdown value. There's no such thing as a made starting hand in razz and board texture (both yours and your opponent's) on the later streets is a massive factor, at least as important as what your down cards are.
