Question on which counting system to learn?

Hello...I have played just Basic Strategy for sometime now and want to add counting to my game. My question tho is which one of the various systems best fits this game which is available at the two casinos near me.

6D, S17, DA2, DAS, SP3, SPA3, NS, bout 65-70% Penetration

When I go to Vegas the place I stay mostly offers this game:

2D, H17, DA2, DAS, SP3, SPA1, NS, bout 50-60% Penetration

I am more concerned with a good count for my local casinos...but would any system work decently with both the above games?

Thanks for your time

How often do you play 2D,if just once or twice a year,stick with Hilo.If you play a ton of DD,learn Zen

65-70% pen in a 6D is Horrible

P.D.

I generally go to Vegas 4-5 times a year sometimes more if I am having a good year betting NFL games I may have underestimated the penetration...figured it be better to guess lower than higher.

Penetration is the name of the game.You Must be accurate at this.
Since you play fair amount of DD games,Zen is the one you want.

P.D.

Prince D' is 100% correct.

If I go with Zen

If i go with Zen which of the versions should I learn? I have Blackbelt in Blackjack with the True Edge Indexes...but from trolling a bit on here I see there are a couple different versions.

1) True Edge
2) 1dTC
3) 2dTC
4) Unbalanced

Which would you all recommend?
