I've argued this specific subject far beyond pointlessness, but I just wanna throw something in.
Swinggcat's 'Demistyfying Charisma' is a very powerful insight into the subject of natural vs. canned, and if this subject is of interest to anyone, I strongly recommend you familiarize yourself with it.
That being said, I'll start with the base of my argumentt:
Anyone who claims to use no canned material whatsoever is full of shit
This is a strong statement, so I'll explain what I mean by 'canned'
If you observe a charismatic person in a social setting, you'll notice that this person frequently uses the same lines while interacting with different groups of people. It may be a joke, a specific response to something people say frequently ('are you gay?', 'why do you wear this necklace?' etc.) or a story they like telling about something that happened to them earlier this week. Notice that at no point is this person lying: the stories and responses are all true, it's just that they are recurrent in social interactions. This is what I consider 'canned' and ALL charismatic people do it without being consciously aware of it. I even consider 'Hi' a canned line, simply because it's RECURRENT. I'll use an example from 2 days ago:
[Ace-noticing an interesting piece of HBs attire] There's something I want to ask you: what is it with your dress/your hair/your shoes?
[HB] Well, I thought the shoes would go well with the dress/I thought it would be cool to have a streak of green hair to go along with the dress.
[Ace-smiling] Oh, you thought that, did you?
The last bit is something I consider a 'canned' line since it's my standard response to qualification starting with 'I thought...'
At the same time, rolling exclusively on 'canned' material is impossible since it doesn't allow for a 2-way interaction. Hell, I use canned material but at the same time I'm comfortable improvising. All of my stories, true though they are, make me sick simply because I've regurgitated them hundreds of times. They demonstrate my personality in a consistent way, they get the sets hooked, they get the job done far more consistently than any 'natural' sarge I've ever tired. At the same time, the parts of a sarge where I improvise are the parts I enjoy most, simply because I'm finding out about another human being.
So what I'm trying to strain out here is that every pickup artist worth his salt mixes natural and canned. If you have a prepared sarge-plan of a 1-hour interaction you'll fail miserably because pickup is a 2-way street and not allowing for any degree of spontaneity will have you crashing and burning like an Italian fighter pilot. At the same time, if you're making a point of never repeating anything you've ever said at any arbitrary point in the past, you're wasting a valuable asset. I admit that improvising is fun, but at times trying to come up with an original and witty response while you have two perfectly good canned lines that have worked wonders in the past is making pickup more difficult for yourself. And that's not what pickup is, you don't get extra points for purposefully shooting yourself in the kneecaps. What's next? 'Im gonna sarge this HB using sign language, but I'll be hopping on my right leg while my buddy lobs grenades over my head'. It just seems slightly pointless to me.
Bottom line: I don't get natural game. I understand that when you're improvising it's useful to have the right mindset and frame and there's no denying that, but I just fail to see the point of trying to come up with a better respose to
'I thought this necklace would go with my belt'
when I have a perfectly good canned response up my sleeve.
Perhaps this whole thing is just a misunderstanding of the term 'canned' in which case this post was pointless, but if I ever get somebody to explain to me why 'natural' game is so much better and why they hate 'canned' material like it was a cross-breed between Hitler and Skeletor, I'll be able to die an enlightened man.
Edit: I read Rye's post and forgot about it. Pre-packaged STORIES are shit to the point where I won't waste time proving it, pre-packaged IVDs (derivatives of the cube and best friends test) are AWESOME.
I'll stick to 'canned' as your OWN memorized material including IVDs plus standard one-liner responses to recurring situations.
Also, Stetson, calling someone a 'moron' is below your level, so I'll attribute it to you not paying attention to what you were writing because you were getting a blowjob from two Finnish blondes while typing

. Just don't do it again.
