Re a previous posters comment, a 25mm will make sod-all difference to aerodynamics. I prefer 25mm tyres because the bigger air pocket means that you can run lower pressures and hence get more 'rubber on the road' in comparison to a 23mm, so does improve handling in corners. I use a local circuit for training with a fast 180 degree bend - people crash regularly in races - and you can test the limits of adhesion and handling. A 25mm tyre is more predicatble and doesn't feel like giving way when you heel it over. A PR2 in 25mm would be a great tyre for RRs on typical UK roads
700x23c or 700x25c

Thanks Monty Dog, the question is now, run 25c on both front and rear or just the rear?

If you're over 70kg I'd go for 25mm F&R.
Trying a cheap pair of 25's MAY be an option, but remember that you get what yer pay for and they're not likely to be as 'supple' as more expensive tyres.
I currently run 23 PR2's, but will probably pitch up to 25 PR2's(or 3's when they're available) for next year.The only downside being that 25 PR2's only come in black !
