I've been playin for 6 1/2 years, and I cant figure out how to get more rolls, my single stroke is pretty fast and I cant do triplets,quads, and fast doubles with my foot. Dont get me wrong I have an awsome pocket and some rolls of my own that are good but some of them seem elementary and I hate that. So how can I firgure out how to do more advanced rolls, please help me!
