As good as they seem to work for most cars but not all, I do not have interest in using Cal-tracs, South Side bars or old school slappers. Just the old tech leafs. The launchers are a little heavier, not as much as it sounded at first, but they already are razor responsive with a little test and drive yesterday to the Astoria reunion in Astoria park. I'll see how the track time reflects the change. I'll find the 10 Lbs somewhere I'm sure. LOL.
