Is it worth upgrading from KO Full to UBZ II, mainly for 6 and 8 decks?
For full play and backcounting, what`s the difference in SCORE between the 2 systems?
if your then just playing 6 and 8 decks, then its not worth learning UBZII if you already have KO down pat. Single and double deck is a different story though. UBZII is probably worth learning for single and double deck.
