tl;dr
* My two typical pre-selection strategies: group of guys, group of girls.
* Use fatties at bars to create connections, draw attention, and disarm hotties.

As we all know, pre-selection is an essential tool to non-verbally display social status. But just like your winter coat, you gotta change it up once in a while. Can't keep rockin that same shit or you'll look homeless. However, as much as I've heard about pre-selection and it's glory, starting my RP journey almost 2 years ago, I've yet to come across solid strategy on how to manufacture it. The Machiavellian I am, I came up with something that works for me. I have two primary methods which I'll keep short. They're my "Dogs" and my "Cats".

My Dogs are these 4 guys I've trained in the gym over the past year and a half. We reconnected recently and they've kept up the good fight. All once athletes that now keep pulling at their Tshirts to make room for their massive biceps. Plus they're diverse as fuck. One always rocks a turban, another blacker than night, we run shit and always have a good time.

My "Cats" are two ladies. One tatted up, the other a fair beauty. It's a hot single mom and her friend that I've befriended, inject RPW values and try to find dates for (Not an easier way to open up to a group of 20 people or more than going up to one of the guys and saying your friend wants to fuck him). I call em my cats to their face because as much as they're pussy, you wouldn't fuck a cat. Which pisses them off plus the tension keeps them hungry.

The alternative is to go out solo, but then how do I display pre-selection?
Both of the previous methods rely on creating a scene, an atmosphere. And what do we all know that always creates a scene and includes it's own atmosphere, and potentially even a gravitational field?
FAT CHICKS
Yup, fat chicks are great for this. Big, loud mouths, clown makeup and bed sheets covering the crevasses in their gut, when I see one in a bar I get a bigger grin than even a Japanese whaler would. They're as big as my Dogs, as loud as my Cats and everyone knows I wouldn't even touch it with the bartender's dick. It shows you're social and gets eyes on you. It's really that simple but effective. It warms you up socially, you're not gonna get denied conversation, and every hot girl is jealous that the hamplanet is the one that gets to talk to the hot, jacked guy. Like some fucking SQL injection you broke the He-Just-Wants-To-Get-In-My-Pants-Reject-The-Player-Now alarm on every girl that saw you. You just wanna talk, and the next group that you walk up to will quickly quiet down to hear you talk when you arrive. Obviously this doesn't work in EVERY situation (If you're at a loud bar or club, proximity is everything), but it's damn well useful in the utility belt. Mind you, I go out solo often enough and it works. Sometimes I even get some business leads out of it. Sure as hell beats that "strong silent type" character alone in the corner, thinking you look cool, drinking his beer alone bullshit. If you're not social at a bar, you're useless to everyone there but the bartender, and it's all about SMV.

Lessons Learned
* A tried and tested use for fat girls other than lamp oil.
* Similar to the strategy of talking to the ugly girl in a group to get the hot one, they don't have to know each other or even be close to one another. Being visible is enough for the hamster.
