Yes, I have also noticed that people here are "against" Mystery Method what's that about?! I'm new to PU and yes I think mystery is a little weird but his method works ain't it?
Anyway, you can go with an opinion opener or maybe a direct opener something like "I saw you and I think you're cute but I want to see if you're friendly too (smile here!!!) I'm BLAH BLAH"
If you want to cold read then after the opener say something like "you know... you seem friendly/good girl/bad girl/smart/adventurous/etc
cold reading isn't hard as you can see.
And about transitioning, as juggler says "Transitions are for the weak minded." so you can just start with a story "do you believe in god?" - yes/no - "listen to this..."
Good luck!
