Re: Girls in group: handing out business cards?
It's an interesting concept, but I feel it falls a bit short. Beings that you approach with a business Mindset it will be tougher to transition into a natural convo later. It'll definitely be easier to get phone numbers, but the phone number isn't very important. It's what you do before you get it that's important. I'd rather have 2 or 3 solid phone numbers than 10 flaky numbers.
Group theory works just fine. You see, if she has a bf and he's in the group it'll be fairly obvious. If not then just ask how they all know each other. If she has a bf at home then that's what bf destroyers are for.
Trying to come in under the radar with the phone number so the friends don't find out is not something you have to deal with. If you run group theory properly then her friends will like you and practically tell her she better get your number. And they will speak highly of you when you separate. Why not take advantage of this? I mean, if you want to talk about peer pressure than that's the best kind.
You should reach a point in the interaction where everyone knows you like each other and that's ok. I mean, at some point you have to at least let her know that you like her. Can't hide it from her forever.
Your approach definitely has potential and as long as you fill in the gaps where it comes up short it'll make for an interesting play in field.
