You need to know how wide your rims are, to make an informed decision about which tyres to use.
So you either need to get your Google on or ask V-Sprint.
Sheldon's table lists what "works" (and he notes that he errs on the side of caution); the table attached was prepared by someone on here and details what's "ideal".
To answer your question (without knowing what your rims measure, but assuming they are at the narrow end of the scale), I'd say that 25mm will work reasonably well and that 28mm won't kill you (in the face with fire), but won't offer any advantage over a narrower tyre and likely handle worse.
Of course not, that's what it's all about.

23mm would be the "safe" choice.
