The "Control Asphalt Pads" are so far the best pads, although the wear, even with proper "use", is quite high. The newer pads that are used with the Yellow and the latest "Endurance Pads" way too hard. Nim out in hand and compared !! Make so much noise, but let the stress it brings the body. I run for 5 years and have very good sticks, I mean, among others Exel (high carbon content). I'll tell Exel also my experience and ask them to the experiences of Walker heard.
