Well if the ball is perfectly going straight down the middle, no flipping will save you. If the tilt allows you want to do a slide save to get the ball over to one of the flippers. If tighter tilt, a slap save will move the ball to one side just a hair to be able to get a piece of the flipper on the ball. When going perfectly straight down the middle I like to slap the game from one side on the flipper button, getting a piece of the flipper on the ball and then letting the ball dead bounce off the other flipper on a deflection.
I call it perfect drunk. For me it’s around 6-8 beers. The perfect mix of confidence without too much loss of your wits. Haha
