+1, not yet anyways. The Q2's are great tires to start out with at the track, you can take them all the way to the bottom of the "fastest" group, depending on the track/groups.
Just remember cold tires are your enemy, espeically cold, unscrubed tires at the beginning of the season on a cool day. Take it easy on them until the day warms and you get a few good laps in.
