TH,  I find out what I am bowling on first.  The pattern length and the ratio.  At that point I determine what the proper exit point is on the pattern.  I already know my lateral movement tendencies.  I will make the first shot and read the rack and the ball going off the back of the pin deck.  From there I adjust.  I am always adjusting as the conditions change.  The first shot is straight up the boards.  I then read and adjust.   Here is a typical process   House shot 39 ft pattern.  Exit point should be the 8 board at 39 feet.  I drift 2 to the left.  So I line up on 13 throw the ball.  My slide foot ends up on 15 ball goes over 8 at 39 feet.  Let's say it goes brooklyn.  I move my feet left 6 boards and angle my heel 1/2 board.  This should put me in the pocket and still exit over 8 at 39 ft.  As the night goes on I adjust to changes.  I adjust ball speed and timing by raising and lowering the ball.  Entry angle is changed with hand position.  Skid. hook and roll is adjusted by target distance length.  I use a combination of things taught by Joe Slowinski and Dick Ritger.  The system works equally well on house patterns and sport shots.

All I have is a B game!   

Seriously though, trying to go straight up the boards is my bane.

B game? That's all I ever get to play. Well ok sometimes get to play a C game.
