I'll look into the tracker and Q JLS. The JLS intruigues me simply because I don't have many discs and am looking to try out some more brands.
I take issue with any other Trackers other than the X and some of the first run Zs (the red ones that just say DISCRAFT across the top) being compared to the Buzzz. Most are considerably more overstable and don't hold a line very well.
