So often the move to stop 7 pins for me a lefty is to move slightly left and maybe get the hand a little more direct! It happened last night. Strike one lane 7 pin the other strike then 7, then a move slightly left and more direct 4 bagger. (should have been 8 with brains applied or at least 6!).
It seems so often the ball on many league conitions is a half board light and too much on the adjoining pin of the pocket. 2 for me and 3 pin for you.
Interesting.. In juniors and college, I was always taught 7up:
For righties, 7up, 10 back: stick a 10 pin, move back roughly half an inch to change the entry angle. For 7 pins, move up half an inch.
Lefties need to reverse that. 7 pins, move back half an inch. 10 pins, move up half an inch.
Agreed totally about entry angle, but going more direct may not be the key there yet, because you already have a good line to the pocket; it is just that the ball isn't finishing in a strong position. If I leave something else in the back row, I'd stay there until something along with it is left (read: 4 pin, 6 pin), then consider the move left or right, or ball down.
