Trying silvers and greens back to back, no difference on track
Schu Greens

However, silvers/greens vs ride red springs, there is a difference. The Rides are more progressive, so even though the rate is similar, the feel is quite different on track. They have their place (particularly very bumpy or very low traction, IMO)... But 95% of the time on asphalt, silvers are the go.
