I'm planning on getting 2-pc. leathers soon. Does anyone know first hand which are good for the summertime heat, durability, and nothing too expensive? I had my eye on a Alpinestars TZ1, Joe Rocket GPX, and the RST. I saw an RST in one of those U.K. Magazines but no dealer I know carries them, I heard good things about them and they look good plus there dirt cheap.
