A few of us found the same thing Shawn. During club races we didn't push, we got very loose around 6 min in and hung on for the last minute. This was due to lack of grip and the soft tires picking up dirt over the run and not wearing down. When I asked Paul about the tires he said that the super soft rear would be better for the conditions. During the WCICS the grip was high and the soft worked better.
Low grip the softer the rear the more grip
High grip the harder the rear the more grip
