2 more cents: if you are missing an angle but hitting a spot- my past experience tells me that your feet are tooooooooo fast. your feet are getting to the line ahead of the ball, therefore you have to "pull" through the shot- missing left, OR if you don't catch up by "pulling" then you are late and "sometimes miss it in the drink". Either way a move left will allow for more margin of error.
Also- take and turn your whole body toward the 10. Pretend the foul line is on an angle- stay square to the "angled" foul line. This will project the ball on the intended path.
OK, that maybe more than 2 cents.
No charge for the lesson, though. Maybe I should coach and not bowl?
