XXL is right on the money.

In my experience daygaming young chicks the ranking order of what the best opener as far as what ends with the most numbers that lead to actual dates:

1) Something about her you notice and like or find interesting so she is talking about herself. This is the most spontaneous, authentic, and organic opener there really is that shows interest so no surprise it is the best if you can swing it.
2) Direct open ("thought you look cute", "that dress looks great on you", blah blah blah)
3) A prop she has
4) A prop she doesn't have that you try to force her attention on
5) Asking for directions, something about the location you're at, the time...

You notice this opener ranking list follows from:
Most Personable ----------------------------------> Least Personable

All these openers are to get her talking about herself and try to relate experiences so she thinks she is getting to know you quickly in the 5 to 15 minutes you usually have.

The props and dropping bait ala Roosh Day Bang is good for many situations where it is too awkward to go Direct and when you can't come up with a good opener about her personally (these take more on-the-spot creativity and also the most charm and smoothness to really pull off) and sometimes you have about 2 seconds to decide to approach.

Krauser lays out how he has trained himself to come up with quick cold read stories in his head in a matter of seconds with he sees a chick so he can approach with some personal material. He lays this out in Daygame Mastery which is a really great book.
