The Revolver 2.0 will be the control tyres you must use for this 2011 Proline Classic Challenge in Slough.
The 2.0 is different : the Revolver 1 is a flatter tyres. My opinion is that this Revolver 2.0 would be a good choice for the fun next week end in Slough. The stock inserts that come with are the blue Closed Cells.
Last year, the Calibers wear to fast and not consistant.
I am a bit sad tonight because I can't come in Slough this year. That's a very good track, not to much difficult to learn and drive but it's hard to go as fast as the best racers. Andrian and his crew are so nice.
Have fun !
