Ok so i thought up a new routine that builds off of the mystery method neg where you take a girl's spot. Basically you walk around with a roll of raffle tickets. (Still havent thought of a solid explanation for having it, I'm thinking a friend borrowed it and returned it while we were there any ideas are appreciated) I think the roll of ticket would be a great prop. People will want to know what it is and so you may be opened by a set. Also you can have the girl you are negging hold it while you talk to her friends so she doesnt bounce.

Here is the basic routine:

Open the set and reach the point where you want to lockin.

"out of the blue" say hey and give everyone in the set a ticket. Then do a raffle in your pocket, of course rigging the raffle so that the target "wins". Then you can say give me your hand, stand up, spin and then take her spot. My thoughts are that she is more likely to do as asked when she "wins" your raffle. Also it serves as a double burn as she finds out shes not getting anything, instead you are taking her spot.

Anyways let me know what you guys think. Anyone who wants to test it be my guest.

lol

I think it's great.
Maybe the reason for having the tickets that you said would do.
