The £600 one? Why not - just make sure you stick a good tyre on it, if you're outside and inside consistently try and get hold of a Vittoria Crono as they're fine for both.
No, but you wouldn't want to risk blowing a CL outdoors during a flying 200 whereas a Crono would be fine. Look harder for the 22s as they do exist still, maybe eBay?
