Flipperi

The name means what you think it means: the Flipperi is Prodiscus's dedicated flippy driver, and it turns over the moment it leaves your hand. With low glide and essentially no fade, it holds whatever right leaning angle you give it all the way to the ground, which makes it one of the most honest roller discs around. Slower arms can use it for turnover distance, and everyone else should treat it as a specialty tool for rollers and hard anhyzers.
