$$/hour
OK, now I don't know exactly what your goals in playing this game are. But what I want to point out to you is that while it is true that for your game:
8D (or 6D for that matter), H17, DAS, etc with a 1-2 spread wonging in at TC =2 and making max bet at TC>=4 using HiLo will net you roughly a 1% edge, your return with a $10 unit is a lowly $2.48 per hour.
Upgrading your skills to Wong's Halves Count (which is a damn good count by the way, used by many great contributors here), a balanced count with a BE very close to the Uston SS would indeed increase your return. You could now expect your pockets to swell at the whopping rate of $2.55 per hour.
You simply cannot defeat a shoe game with such a small spread. Also, an 8-deck game with 75% penetration is unplayable. A 6-deck game with 75% penetration is borderline even if you had favorable rules.
If your answer is "but these are the only games in town", you may need to decide if you are truly an advantage player or really a gambler.
My advice is this: Get yourself together about $5000 (it doesn't have to be in a sock drawer!). Practice the everliving crap out of whatever count you decide to use, because you're going to risk $5000 on it. Next, go to your local casinos and ONLY play the 6D games, don't drink, and wong into +2TC counts with $20, ramp up to $100 by the time the count gets up to +9TC, and bet down to $10 if the count drops to +1 and wong out if the count drops to -1.
What will this get you? Well, your expected win rate will be $5.70/hr (we're getting close to minimum wage now) and if you can log 1000 hours over the next year your chances of busting your $5000 is about 8.5%. You have a 67% chance of winning somewhere between $470 and $10,930 and a 95% chance of being between a $4700 loss and a $16,000 win.
I'm sorry. Games in the midwest and Canada pretty much suck. There are a few exceptions, but not many. They can be beaten, but it takes some work.
As far as Dr. Harris' systems, I'm not sure where you can get his books. Seems like maybe bjrnet has them for sale? Not sure. Try doing a google search. As I said, I haven't seen or heard from him on Green Chip in a long time. (Although I was gone for some time as well.)
Good luck to you.
