Rules: 2 Jokers per deck, 6-8 decks, double any 2, 2-1 player naturals, hit soft 17, no DD after splitiing.
H/A is 1.96
Stand on all 17's H/A is 1.78
With surrender added to stand on 17's H/A is 1.45
DD after splitting decreases H/A by -0.1
Paying one extra unit for BJ (ie, 3 to 1) decreases -1.25 per each extra unit added.
Since no one in Calif uses two Jokers it is my understanding that the difference (using only one Joker) is nominal. The trade off for the Joker up in the bankers position and the less naturals equals out.
