last year I lost my Buzz GT pretty soon after I bought it, and shrugged it off. Have to say that after grabbing one in a trade, I'm glad I re-found this disc. The GT is more overstable than the Z Buzz. released flat, it crawls itself to the left, but w/o any hyzer angle. It just walks itself on an overstable curve... I think the GT thumbtrack creates "deadness" in the disc, which lets me rip into it w/o it getting squirrely @ all.
Just sharing my "re-discovery" of this disc. For Buzz lovers, it might be something they like.
