Im good looking, tall, strong and lean, and have some game but still a bit of an AFC(i think)
So a week ago i got this girls(looked HB:7 big juggs) number after having a fun conversation, then we chat now and then, then we went out in a group of friends. That night we missed an event because she was late (didnt make her feel bad) so we all just went around clubbing. Also during this night i realize she isn't great (id rate her 5.5-6). She leaves early. Then in the week she texts me a lot! I was already not too interested in her at this point. This weekend we went out, 6 of us, my friend was gaming her friend, and another was gaming another. In this circumstance I'd go for her, to help out my friends. Until my friends girls decide to leave, so i leave with my friends, and she leaves with hers(though she even tried to come with us). Now how do i let her down nicely for my University status with other( great) girls?

Also during this week i met a girl in a little house get together/party met this HB9, gave me loads of IOIs(lol not too familiar with terms) we play a little game(big group), then the party ends(the IOIs happened very late, she leaves early.) I see her during uni now and then but haven't had enough time to get into a good conversation/number close(due to studies and different classes), i know she's melting for me, and i just need to get in there. Will this be affected by the other game? Can i use this to let the other one down? What is the best course of action? Bang the first one than go for this one lol?

She's not your girlfriend. You've not even kissed her. You HAD interest but you never ACTED on it. You have nothing to feel guilty about.

Score the one you're interested in and it will drive the HB5.5-6 crazy, wanting your dick all the more. This way you can just have fun with various women and fuck the chick with big tits when you're twisted and think nothing of it. Just play the field man. Make it clear you're not into relationships and no one will be upset with you. Just give them some sob story about just coming out of a relationship and she broke your heart or some shit like that. If you're hot then chicks dig that shit, they'll be thinking they can "fix" you which creates more attraction.

Thnx for the reply, I like what you said lol, specially the heart broken bit. Im really unatracted to her right now. So do i just keep it silent? Because i think her, the HB9 and me might b at the same party tonight... and many more from my uni. I should just be social and game who I want right?

Do whatever you want, bro.

You have no obligations to any of those girls. The HB5.5 is just a clinger. She probably knows this unconsciously and will hang around for the night you're wasted and make that one mistake with her. It's not your problem. No matter what you do in that situation it can only go bad for her. Either you flat out tell her you're not interested and really upset her or you fuck her, play it down a bit and try forget it happened(And her forget). The latter is probably the better option plus you have someone you can fuck when you've got the excuse of being really fucking drunk and lonely/horny.

No idea about the HB9 but don't get attached, especially if it's your first year of college. Chances are the HB9 wants your dick and wants as many dicks as possible -- hey, it's college man. People go wild in college especially women!! Take her up on it if it comes your way. I wouldn't get too hung up on her though, keep scouting for talent and see if you can do better. A real PUA won't just take what he knows he has, he'll try and go for the challenge and get the hottest chick there.
