Honestly, I'm a liar.
Spin without a doubt transfers. It's what makes a lot of banks possible. Bank a ball into the same spot on the rail with inside English then outside English. Then both a different speeds. You'll see real quick spin transfers. And honestly I don't need a scientist saying it does or it doesn't. I know I need spin for this shot, I'm gonna use spin for this shot. I don't care why I need it, I just know I need it.
