I've thrown the Buzzz, the Stalker and a Wasp. The Stalkers are awesome because they are more overstable then their Z counterparts. The Wasp was super awesome because it was overstable like the old opaque Z models. The disc I'm most excited to try in the lineup is a Force. I'll have to wait till somebody near me has one that I can go throw for fun because I refuse to spend the money on it.
