great responses... thanks all.
i usually do a very tame neg in the first minute almost every time, on an 8-9 i'll use in my opener sometimes. (really my goal is 8-9 so although i agree i don't need to neg 6-7's, i do for practice for when the real deal comes along) -- mojo nice call on classifying 9-10. i've only seen a couple 10's in person in my life and only a few 9's per year.
i have a good neg story from about 2 weeks ago (first 9 i saw in months out) i was at a resturant bar and i saw HB9 and after opening, i told her she seemed super nice. before she could shrug me off as an AFC, i kind of turned around (punishment for her non-verbal shrug to me) and said "too bad nice girls aren't my type." she immediately looked at me baffled and asked why i wasn't her type. i told her even if she was my type, i don't go for young girls as she said she was a college student (yeah right, i don't like young girls lol). "you're just a baby, i need a real woman." she looked completely puzzeled, that 'i'm everybody's type' look. at that point she started leaning towards me and asking me repeated questions when i told her, "wow you are nosy aren't you". i smiled playfully when i said it of course, and next i opened up a little and said, okay, let me learn more about you, and i proceeded to try to read her personality via analysing features, body language, hands, psych tests... 5 minutes later, after she told me some things about herself, i said "maybe you are alright after all, maybe i was wrong about you, you do seem a little adventerous and that's cool" then i gave some slight kino. that was the first time a 9 i just met ever gave me puppy dog eyes in my life. and i know the negs made me seem like a challenge. she was with me about 15-20 minutes. i was riding a high.
of course i blew it with her by ignoring her friends as they wandered off (stupid stupid, i was just so excited by her reaction i lost focus argh!!!) when they came over and grabbed her arm to leave, but that's a whole different story i'm trying to put behind me

in retrospect, i should have called her out for ignoring her friends, something like "wow, do you always ignore your friends to pick-up guys at the bar?", then tried to entertain her friends. but really i'm just happy to be progressing and next time i'll be that much better.
anyway, i will keep the frame advice and all other points you guys made. i think what i take away is that i should stick with very tame negs and back off the dogs a little so i can stay in my frame.
btw -- vector great advice and i LOVE the wipe the face neg, classic!
