You shoot it with top left, not top right. Top outside will get you more curve action and will slow down the ball after it curves and hits the rail.
Absolutely correct.
In greater detail, so the 2:00 folks will realize this is a very different shot than the one they're talking about:
High-right will not get the pronounced curve, because when the CB hits the first rail, the spin pushes it to the viewer's left, and the follow doesn't have the chance to achieve that masse effect. Because the right english pushes it to our left, and the follow is acting to our left (the direction Efren shot it), the follow will speed up the CB a lot, and the running english will carry it way uptable off the second rail, unless you hit it very softly, which Efren clearly does not.
With high left, the left spin causes the CB to come off the first rail heading due North, or maybe even slightly to the viewer's right, but the follow is still on the ball, still spinning directly away from where Efren stands, and the follow overpowers the ball direction, curving it back in toward the side rail. That's why you see the pronounced curve, and that why it loses so much speed (direction off the rail and top-spin working against each other, not with each other). That's the only way to hit it this hard and still float delicately into position the way he did.
Good catch, cuetechasaurus.
