Aside from canned material, most of the pickup arts teaches you the proper way to DELIVER what you have to say, rather than telling you the stuff you should be talking about. Sure, there are "DHV spikes" that tell you to talk about how you are popular with girls, how you are a leader of men, etc. etc., but what themes are you supposed to focus on?
I'm sure you can easily compile a list of 10 things that you are passionate about. You could talk about these topics on and on unless you were a passionless robot

. It'd be even easier to compile a list of 10 things men in general like to talk about. If you learn about these topics, conversing with men becomes easy and you never run out of shit to say, provided that you developed at least a little bit of social intuition.
Compile a list of 10 themes WOMEN are passionate about, and do a little research on each of these topics. Once you do that, you can talk to women for hours and hours on end. Combine this conversational ability with pickup and you're unstoppable.
And, if you haven't already done so, find out what YOU are passionate about. Don't forget to talk about THAT stuff. Conveying passion is an ultimate DHV.
