POF opener... 100% so far

This Opener I have been using has been a killer. I sent this out to fifteen girls and so far have gotten fifteen responses and n-closed four of them so far.

I send them a message titled "Do not open this : )"

then the message reads
"Ok now that you didn't listen to me already : P this is going to sound super weird but I saw your picture and just had to say that your hair looks phenomenal"

It works very well for me since I have long hair it gives her something to comment back to me about rather than just a thank you.

Nice Opener, I know I can get a response

i just sent this to a girl less than 5 minutes ago..and got an instant response but i changed it up talking about her eyes instead of her hair :P..

she responded "lol, anything that says don't open this... i gotta haha. but thank you "

what should i hit her with
