being solo is daytime is fine if it's necessary, like when you go about your business and spontaneously strike conversations with girls on your way. but when we talk about hitting up the streets alone just for the sake of pickup it just sucks compared to rolling with your friends. no question about that.
there's nothing better than hanging out with your friend just shooting the shit and laughing your ass off and casually engaging girls around you [throwing out comments/questions and flirting]. it's soooooo much better. i mean, 2 cool guys having good time is way different dynamic, if you do it right. those you say it sucks either create too romantic vibe with the girl evading their friend from ruining it or they roll with not cool friends so it's awkward.
it's lame when you're having boring conversation with your friend and then you ditch him to talk to a girl while he stands there like a moron while you're trying to game this girl for 15 minutes. of course he's getting impatient watching you working hard some girl. that's lame. or even, he comes up and just stands there next to you waiting for you to finish. ugh, that's yuck, that's not how you do it.
instead...
it's cool when you and your friend build fun little vibe together and suck girls into that. so..
you both chat up girls around you and you both flirt with them. or.. you go up a girl and you you point at your friend saying "hey i'm not alone here like a lost little kevin, come meet my friend" then you take her to him and you both talk/flirt with her. or.. each one of you talk to their girls and then introduce them to each other.
either way you both mess with girls a bit, use your inside jokes she doesn't get so she trying to get it what are you talking about, you asks about her friends, blablabla... so it all looks like you're known each other for years. the vibe is cool and friendly, not seductive and romantic. you don't get seductive with the girl when you got your friend next to you haha it's common sense. the whole point is to come across as cool, show you have cool friends and make the girl(s) comfortable with you to meet with you again in more private atmosphere where love takes over
in short, you can walk around solo scanning environment for girls or you can have a good time with friends AND harass girls at the same time...
btw,
you don't need a friend with with "A game". your friend just needs to be talkative cool friendly and social. after all it's just a casual conversation/flirt. not some kind of advanced chess game. when he asks you why you talk girls you just say something vague like "dude i'm single and this girl had such a beautiful XXX". when he sees he's still alive after few interaction he will get with the program. personally, i'd take anyone, just any chode, i'd help him bring his cool personality to the surface to accompany me simply because it's way more fun that way and when i'm fun girls feel that way too.
of course, the best daygame scenario EVER is rolling with girls
