Saw a picture of a player with his arms crossed over. Looks like there may be a "don't cross the beams" mode where the flippers are reversed. That will do my head in as Black Hole lower playfield always did.
that was Keith Elwin, top pinball player that is also making the custom Archer game. Apparently there is a mode once you achieve some goals the flippers cross - maybe a crossed proton beams - sounds like fun.
