The Revolver will only work *best* if there is very minimal surface dust, if any; and the track is starting to groove.
Otherwise, you'd want the PL Caliber.
Caliber is more like the CityBlock, but has a bit more forward bit and a smoother rotation curve.
M3 works like AKA "soft" for the most part.
M2 would be the better choice as you work your way into Summer racing or if you have a track with a loose surface that the tire can dig into.
