I would probably say that "conversation demolition" is a pretty under-rated product, and probably the most useful one you can get in terms on fundamental skills with good practical examples instead of reading PU books.

60 is also very good for sexual escalation and stuffs that cut through bullshit.

I handed both books to a friend and he told me he got laid without difficulties at a night party and got somehow "de-toxicated" from the PU crap he read through all those years...
