8 deck S17 game with one deck cut off or 6 S17 deck game with 1 deck cut off. I can hear Automatic Monkey screaming penetration, penetration, penetration but after my last trip, I'm pretty convinced that distribution plays a bigger role than one might think. I have a hard time believing the advantage when the count is good is just .02% for 6 decks vs 8 decks after noticing that over many hours of play, I seem to do better at the 6 deck games.
