Which Graph Tech saddles for a CV 50s Strat?

[rugbynyc]

I'm thinking about replacing the saddles on my CV 50s strat with GraphTech graphite saddles.

From the Graph Tech store at MF, it seems like there are a lot of different sizes....does anyone know which ones will fit the CV50s Strat?

Why are you replacing the saddles? If you are looking for more sustain and better note clarity then replacing the tremolo block is the better solution.
