Theres a slightly wider base for drive and just enough rake that combines with a thinner tip for a tighter radius on turns and less drag. The 8. 5 Tracker is for flatter rocker boards and extra long (11) gliders. The 9. 0 is more utilitarian and can be used for shorter longboards for driving down the line speed, nose rides and smooth cutbacks and gliders as well.
