Why in the h*** would you move if your striking unless the ball is laboring or exiting off the end of the lane poorly that you didn't mention. If your striking and the ball looks good leave it the h*** alone. I threw 6 strikes in a row Friday night never moved and inch. Unless someone is playing on your line you can generally stay there a while. Don't make your move off of arbitrary data number of strikes you do it off the reaction of the ball and the pins.
