Yes, swinggcat's book is good.
There are some little bits that go nicely with VAH stuff, like cold reading, belief systems, push-pull, etc.
I really haven't used all of swinggcat's techniques, but he has some really good ideas. Ex. No matter how she reacts, assume she's getting turned on.
This sounds simple, but it can make big effect. If you go out there and think "maybe she will give me ***** shield", then it will probably happen. If you interpret everything she does as trying to win you over and that she's into you, then the chances for positive outcome increase a lot.
But, like anything, it's possible to become the "nasty nerd" to steal an RSD term and try to use this stuff in a negative, ego-protecting fasion.
