Can't be a pocket 6 pin! If it was a true pocket hit you won't leave a 6 pin! If the entry angle is to steep then the ball hits the 3 pin to thin, which sends the 3 pin in front of the 6 pin, but that's not a true pocket hit! If you hit the pocket thin, you're to heavy on the 3 pin, which sends the 3 pin back towards 9 pin and doesn't make contact with the 6 pin! I've left then before, but the ball was jumping to hard at the break point and entered the pocket at to steep of an angle. It does hurt your feeling though when it happens and most people will just scratch there head. That's why so many of the great coaches tell everybody to get in the habit of watch the ball all the way through the pin deck so you can learn what's going on with ball reaction and the necessary moves that you need to make!
