I have been playing single deck games exclusively using hi-lo and all the indexes between positive and negative 6. I have had quite a bit of success, but because of work will be away from Vegas for the next 9 months. I would like to learn a level two count system in my time off, hoping to increase my playing efficiency. I would like a balanced count with no side counts. What systems do people recommend, and how do the playing efficiencies compare between the level two systems and also with hi-lo. And also, how difficult has it been for people to switch from from a level one to level two system. I can count cards using hi-lo and recite the indices without even thinking about it, so it seems the hard part is not to learn the new system, but to get rid of what is already so well engrained. Thanks. MG.
