Eh, I don't really spam approach and have a pretty good success to fail ratio if I eliminate girls who are taken, large group sets, and other sets where there's really low probabilities.
For day game, you might be right. I think you need much stronger verbals to succeed in day game.
For night game though? Non-verbal is king. Quite frankly, I don't think it matters what you say a lot of the time in night game as most of the places with the hottest women are so damn loud they're going to hear maybe 70% of what you're actually saying anyways.
If you have some decent looks and height and good non-verbal communication, it's not hard to get the girl to do most of the talking with saying very little.
From my experience, if you're the more talkative, quick on your ft with verbals type of guy, day game is a better match for you, while if you are less talkative but have really good non-verbal communication, you can be pretty mediocre at having a conservation and still do very well at night game.
I prefer night, but I treat it like day. I only choose venues with large out door areas.
The bolded part isn't actually true, especially if you're not tall or white ---
