I made a mistake in buying the M2 compound for my Revolvers. M3 is the way to go, but i've pretty much stuck to AKA's ever since. They last a long time and they wear very evenly. Also, the tire is mostly supported by the foam instead of the sidewalls, which in my opinion makes the tires more forgiving.
