Fuji Track / Fuji Track Pro / Fuji Track Classic

Just so you know, it might be worth going one cog either side of the 18 in order to maximise the number of skid patches you are going to get. I think the 18 tooth gives 2 whereas the 17 gives 17 and the 19 gives 19, just a point to try and save you money in the long run. Miche are good so long as you check them regularly for wobbles. I'm running an 19T EAI (from hubjub.com) or 17t Miche (depends on which hills I need to get up).
Also the 17T will fit straight on without you having to alter the chain length (another plus if you can take the slight increase in gearing)
If you haven't had the lock ring/sprocket off that fuji yet you are going to have an evening of fun ahead of you, they are on pretty solidly from the factory (locktight) so might take some swearing to get it off.
Enjoy.
