Looking at the object ball last is not close to a myth, I have yet to read anywhere where a good player looks at the cue ball during the last stoke. Only time may be during a break or a masse/jump shot
I personally look at the OB last, and don't understand how you could excel otherwise.
However, in the "Break and Run" DVD box set, Rodney Morris says that he looks at the CB last, and he mentioned that many of the top filipinos do also. He may have even said Efren does, but I can't remember.
