Nicholas: Being "non-supplicating and aloof" doesn't mean that you can't be warm and friendly, it just means that you shouldn't fall all over yourself to pay special attention to one particular chick just because she's a super-hottie. Don't do little "favors" for a chick JUST because she is good looking, only do what fits in with your personality, and things you would do for ANY chick, even a UG friend.
Style: I agree with this. A mediocre looking guy dripping with attitude may be intriguing and alluring, while a stuck-up goodlooking guy may just seem like an asshole. On the other hand, you don't want to come across as a doormat. The best approach for you, I'd say, is to "warm up." In other words, let a girl think at first that you're aloof or arrogant, but slowly open up to them and show your warm, down-to-earth side. This accomplishes two things: she thinks she's making progress that other HBs don't and it's exciting for her, because she knows you're not like this with everyone. Secondly, you have a very good way of "punishing" her if you don't like her responses (if she doesn't return kino) by reverting to your aloofness for a little while. Experiment with letting her earn your warm down-to-earth side and see what happens. I think if you can play this right (not be too aloof on the opener, but not be too super-nice immediately), you'll get amazing results.
