Hi, BJGenius007, Can you post your hilo indices for double deck with surrendering?
BS for 9 vs. 2 is double for one and two decks, but not for four, six, or eight decks. The Hi-Lo index is +1, so when you hold a two-card 9 vs. dealer's 2, the RC is either +3 or +2. In either case, for SD or DD, the
TC >=+1, and so you double. Once you divide RC by 4, 6, or 8, the TC <+1, so you hit.
While the above is true, as Norm mentions, BS has nothing to do with a TC of zero. You realize that, with the above hand, off the top of a single deck, the TC could be +3 as you make your BS play.

I have never played H17 game since 1990's, so I don't have indexes for 16/15/14 vs A.
I use AccuZen, an multiple parameters Zen with three counts (main Zen, ace, 8/9). Converting Level 1 AccuZen to HiLo, they should have very similar indexes you can use.
16 v T: -2.5
15 v T: 0
14 v T: 2.5
16 v 9: -0.5
15 v 9: 2
14 v 9: 4.5
16 v 8: 4.5
15 v 8: 6
14 v 8: 9
13 v T: 6
12 v T: 10.5
The above indexes are applied to both S17 and H17 multiple deck games. AP using these indexes have 55% to 65% of chance to be right when ace and 8/9 distribution are normal. Level 2 AP (AccuZen Player) will learn a new index for the condition that the remaining shoe are 8/9 poor. That covers the rest 17.5% to 22.5%. Level 3 AP will learn another nex index for the condition that the remaining shoe are 8/9 rich. That covers the last 17.5% to 22.5%. My AccuZen has 10 levels. This is not related to the "level" on level 1, level 2 counting systems.
If you can find S17 game, the remaining indexes that can only apply to S17 are:
16 v A: -1.5
15 v A: 1.5
14 v A: 5
Note these indexes to be used by Hi Lo users using formula TC = RC / # of remain deck. (# of remaining deck initial value is 2 then gradually drop to 1.5, 1.25, 1 etc)

This explains a lot! Based on your theory, I will hit a hand of 4,5 vs dealer's 2 when TC=0 in mid-shoe when I count a double-deck shoe, but will double down this hand anywhere in a shoe when I don't count cards.
This issue is also related to the TC difference before and after the hand was dealt.
I know nothing about AccuZen. I thought you are using HiLo, but your indices match to mine very well. For 6-decks, my HiLo surrender indices are:
16 v T: -3
15 v T: -0
7,7 v T: +3
14 v T: +4
16 v 9: -0
15 v 9: +2
7,7 v9: +5
16 v 8: +5
15 v A: -1
7,7 v A: +3
14 v A: +4
These indices have been profitable for me for 6-decks so far, but I am not sure if they are still good for 2-decks H-17 games. Can anybody verify this?

I recently played a lot of double deck blackjack games but am still not so confident with the insurance index of +2.4 for this game. Mathematically speaking, I recently discovered that the insurance index for HiLo varies with the dealing depth in a 2-deck shoe. The index should be about +3.0 at the beginning and about +2.0 at 75% of the penetration. This seemingly contradicts to the conclusion we had earlier that the +2.4 index is fixed throughout the shoe. Can you help explain? Thank you in advance!
