The BB6 is a low profile understable midrange. Its shallow and thin rim make for an easy grip, whether its a power or fan grip.
This will provide consistent flights, exhibiting a little bit of turn and a predictable fade. Which make this a great disc for straight shots, or a gentle turnover throw, or a hyzer-flip.
Alpha plastic is a premium, high quality blend. It is designed to be a little more firm than Bravo plastic and could be compared to Discraft's ESP.
