I sometimes start of with the Cologne Opener

PUA: Hey can i get your quick opinion on somethin?
(Reply)
PUA: I sprayed a different cologne on each of my wrists and i was wondering which one of these colognes is better?
(Make thier choice)
Now instead of saying that my ex-girlfriends gave me loads of colognes i normally say;
PUA: Really!? Everyone else chose the other one...maybe you have bad taste (Neg..in a playful manner).
Normally they reply with "i dont have bad taste" or "i have good taste"
Then i give the reason why im asking so that it doesnt seem like a cheesy way to start a conversation with a girl.

Sometimes i find it hard to transition from there onwards but i was wondering what you guys thought of it? Anyways to improve it?

Thanks .Cufflink.
