I don't feel very weak when I open or close, but I always have a hard time not reverting to AFC conversation topics and just being boring. I can usually open strong enough and can transition into a number close, but I have a hard time getting non boring good talks on day 2's, or leading up to the number close, or just generally chatting. I even know that what I'm talking or asking about is boring, but I figure boring's better than nothing.

Any suggestions, ideas, or help of any kind?

Day 2, you mean like the morning after? I usually say "what's for breakfast" that can be followed by "where am I exactly" and/or "do you have a taxi number".

But if you you have anything in common with a girl at all conversation should flow, stop trying to rely on some script and plays to get with women and just be you, or the best version of you.
Best way to get a conversation going is to ask a chick about herself, women love to talk about themselves, their day, something they've done or a place they went to.
As soon as they start talking you can listen and everynow and then it should bring up something that you can relate to and yourself then talk about. And vice versa, voila you are having a conversation.

Day 2 as in meeting them for the second time. And I can ask them questions, it just feels unnatural to me to open someone, and then be like "What'd you do today?" asking women the normal questions that they get asked like what they did that day, or what they do for a living is exactly what PUA forums has taught me to avoid.

I pay attention to about 2% of anything I read on here mate, I am still rather successful and was for many years before I even heard about PUA. It's about being you I think more than anything else, just the best version of you. Sure some peoples techniques work for other people, but there is so much crap I read on here, like peacocking, sure having a little something to start a conversation about can be good but going out with goggles and a pink wife beater chicks will talk to you because they think you might be able to help redecorate their house.

I might be lucky with natural game and I have no problem talking to anyone, but I wasn't always this way up until I was 19 I was more the shy type but I basically grew the attittude of "hey I'm sexy, interesting and people want to be with me" then suddenly I was and they did.

What's the worst that can happen if you are having trouble just now whilst following some of the tips saying to avoid it, give it a go one night asking a chick what she does and seeing how the conversation develops. If she is a student; what does she study; where does she study; is she from that city origonally; what was it like growing up where she came from, if she works; what does it involve; what are the people like; does she see herself staying there; what would be her dream job. From just a few questions you can get to a point where she should be doing most of the work in the conversation if you have trouble talking about yourself.

Edit: Oh I was joking about the day 2, I don't generally arrange second meetings with women anymore unless the sex was really good. Which I kinda shot myself in the foot with as I forgot to even think of taking the chicks number from this weekend and spent an hour on facebook trying to remember her name.
