I was wondering what the best system would be for a double deck game that has either S/H 17, DAS, No surrender. And what bet spread do you need? I've heard anywhere from 1-4 to 1-8. I thought Hi-Opt II was the best count then I heard that it wasn't good because you couldn't be accurate in adjusting for the count side-counting aces. Also for all these various counting systems do the index numbers change for the strategy variations? I assume they do and how do you find those?
