The striker is definitely a highly controllable disc, particularly in the GL line. I think mine is in the 167 - 169 range. Been experimenting with and enjoying a 170g GL Riot lately as well. It flies like a speed 11 striker and looks pretty cool in banana yellow to boot. Both discs are flat topped rather than domey, and I've heard negative reviews of the Riot in the past, so maybe I've just got a good one?
