Story time answer: back in the late 90's when Gateway started they literally were a dude making discs in his basement, and every early run of Sabres had something not right about them while he learned how to mix plastics. We used to sort them into to two major categories; gassy and streaky. The gassy discs had visible gas bubbles (this was back in the base plastic only days and you never had visible gas bubbles in DX plastic so at the time is seemed like a huge issue) and the streaky discs had streaks of resin that didn't mix in completely. The streaky thing also happened on Discraft Tournament Pro plastic (we called it "Cyclone dust") and Millennium/Pro plastic so while the Gateway streaks were pronounced, it didn't seem like as huge an issue as the gas bubbles. You just had this "flying through space" screensaver look happening on your disc.Chalky wizards. Explain?
The Gateway spin on gassy and streaky was that the gassy discs flew farther and the streaky discs had better grip, so I knew guys that looked specifically for both kinds.
Fast forward 23 years; Gateway still will from time to time not get the resin mix right and will run a batch of streaky discs. They just call them "Chalky" and sell them. Is it an accident that they market, or is there demand for them so they do it on purpose? Nobody on this board will know.
