I'm comfortably successful with women, even much younger than me. However, my success is in certain settings, and with certain social dynamics. I sometimes find it limiting.

I'm not a good cold approacher, and I've decided to quit night game completely, unless I'm with buddies and the IOIs are very clear.

The thing is I lack the skills to cold open and go into escalation and I'd like to work on that. For that I'd like to read a bit or watch materials that deal mainly in pure technique, not the inner game stuff, as that is quite solid.

What are the best to read/watch in your opinion?

Things like models is just what I don't need. More along the lines of the old "classic" PUA stuff, but those that have withstood the test of time, plus newer stuff that is good and to the point.
