The popular pick up model nowadays is a direct and sexual "natural" game. This model is quite effective and will be successful in many situations; however, I find it can be even MORE effective in many cases to diversify your game.

One great way to diversify your game is to actually be indirect and non-sexual with the conversation element of your game. I wholeheartedly agree with sexual eye contact and very direct/sexual body language with lots of kino early on in an interaction. However, with that said, sexuality, confidence and aggression are not the ONLY turn-ons to women. Women are also turned on by intellect, humor, and social standing. Instead of using all three main modes of communication (speech, eye contact, and body language) to appeal to her sexuality, use speech to appeal to other aspects of her. Body language and eye contact provide plenty of opportunities to sexualize and interaction; you do not need to sexualize conversation as well; use conversation to appeal to her brain which, believe it or not, is perhaps the most erogenous zone in her body.
