Ido see a benefit to the travel on the TT tracks. There's some decent jumps on the EDT circuit. Some quads need the front to back sag for getting the power to the ground. One track has a couple extreme off camber corners where I think one could benefit from a good bit of travel. Now on an oval, I say the lower the better. My set-up was only about 4" off the track at the front of frame. I never even came close to bottoming out on the oval.
