When you say this, I assume you count aces as a ten and deduct 2-6 for a balanced count. Let me know if this is wrong.
A friend only counts aces. He goes to Vegas once a year, mostly for fun. By counting aces, it is easy even when having a number of beers. He is trying to avoid heat by
always surrendering pair of 8's vs 10 or ace. The win ratio on splitting 8's against a ten is real, but small. He still gets some heat when he jumps to $100 from $10 when half the deck is out and all the aces are in the shoe.
We both shun 6:5 games!!
