Yes, I have an answer
But Bootlegger beat me to it. I would have stood on the 16, considering the count and the conditions you described.
It sounds to me like you are just beginning to learn card counting. How many books do you have in your library? I would highly recommend Bootlegger's 200 Proof Blackjack, Stanford's Professional Blackjack, and Don Schesinger's Blackjack Attack, Third Edition for starters. These books are invaluable for APs, and should be required reading, imo.
All of these books can be ordered from Pi Yee Press, here's a link:

And one more recommendation: consider joining Green Chip - it's well-spent money.
