I myself have only tried this routine on a single chick at a time. I have good female friends, test subjects, who said it was a great routine before I had started using it. I do think it would work on a group, a huge DHV, but it would be much harder to slip into conversation that way. My theory is to experament as much as you can and then share findings, thats what I tend to do. For example chick crack, palm reading etc., works like mad. I said the word palm reading and the next thing I knew the chick was excited, her hand was in mine, and I had just made some progress. Unfortunately I don't know palm reading well enough to use it yet, so I just negged her by saying "Wow, your hands shake like mad anytime I look at them, I'm not going to be able to do this." I know it's a lame line, but I was experamenting to see what routines worked best in the field, I wasn't looking for a target at the time.
So like I said, experamenting is the only way to find these things out. good luck dude
Only few people know that life is beautiful for lacking something. The so-called turning-around is that you not only mithe sun in day time but also the stars at night.
