I slide, jiggle and shove in a big way. In fact, I have slipped small plastic bags over every tilt bobber in my pins to completely prevent tilts and had installed nylon glides on all of the feet.
Been severely nudging and jiggling since the 60's when we used to hang at the pool hall game room and would place those bakelite ash trays under the front two legs to "level" the playing field. You could play all night with a single coin.
