hole card and front loading

Hello

I consider myself a strong �BS� player and a (decent) card counter.
I am very intrigued in other forms of advantage play I have read about like hole card and front loading. But I have no clue what I should be looking for.
The casinos I visit only offer shoe games and all verify there blackjacks with the viewer on the table.
Do I have any hope of finding these types of plays in today�s casinos?
What weakness should I look for in the dealers?
How do I find this type of opportunities?

Any help would be appreciated.
