In pool it is when using a masse. But when a straight shot can't be played because of being blocked by other balls, a masse will be the ONLY shot that can be used. And with Efren doing it, very accurate.
A curved shot in golf as well as a straight shot can BOTH be very accurate. But a dead straight shot is the hardest to hit by most amateurs in golf. Same with pros when there's extreme nerves and pressure at the time. That's why they opt to turn the ball one way or another. Tell me, how do they do it? What has to happen prior to impact and at impact?
