I am hoping that someone with higher math capabilities can estimate my edge as I am not good at determining this.

I use the hi/lo
TC=0 or +1, bet 1 unit
TC=+2 bet 2 units
TC=+3 bet 3 units
TC=+4 or more, bet 4 units
Wonging out usually about -3 or bet less than 1 unit if table min. allows for it.

The game:
2 decks, about 60% pen. familiar dealers often go deeper, as much as 80%
Rules are DOA, DAS, H17, no RSA, no LS, RS to 4 hands total.

I know BS very well, but sometimes feel uncertain about soft hand doubles. If in doubt, I just hit, but there are very few of these plays and its mostly against the 3,4 up card that I haven't mastered yet.

I have PBJ and have learned several of the index figures from -3 to +3. I am adding more as i go.

I play in the casino and can keep the count pretty well despite all the distractions. I tried switching to Halves but it is still probably too soon for that as I lost the count or felt I was inaccurate. Any opinions on using a hybrid of the two counts? I am thinking of using hi/lo but changing the 2 card to +0.5 and the 5 to +1.5. I think this will allow me to continue to do hi/lo for a while and probably reduce my SD somewhat as Halves has a lower SD. At my limited bankroll, I would like to reduce errors in estimating advantage. With hi/lo, several 2s can come out and I would be overestimating my edge. for example, 3 2s and 1 10 come out, in hi/lo thats an RC=+2, but in Halves thats an RC of +0.5.

Heat is not really a problem where I play and most of the ploppies are fairly well-versed in BS and that helps because the more that know BS the better. My reasoning is that its easy to spot a pro in a sea of idiots, but harder if the average Joes all play BS and the pro for the most part does as well. It's less stressful too because I have noticed they harbor fewer superstitions and I don't get blamed for "f*ing the deck" nearly as often.

Thanks for the help.

I don't know about your numerical edge, but my suggestions would be

1) forget about the halves until you are confident in your index memorization; and at that point also forget about "hybridization" of the halves and hi-lo. If you want to change over, just use 2 steps: first change your count values while using the same index numbers. After you get that down, then redo your index numbers. It's not that hard. But it sounds like right now you're trying to rush it.

2) normally a 1-6 or 1-8 spread is used in 2 deck, rather than a 1-4 as you do. However, you say you wong out and go below 1 unit if the minimum allows, so perhaps your spread is okay. Wonging out of 2 deckers, and going below your usual minimum are not things that are easily done at more usual 2 deck games with normal heat, so you might want to look at spreading one to eight and playall at some point. Make the changes before you get heat and you'll be able to play longer.
