Ne Ti dynamic

I've found that I don't really have a lot of conflict between the two, at least in the regard that I think you're asking. Like you said, the two functions work pretty well in conjunction.

And it is all in the demeanor, I would say. It seems to me that the difference is mostly in the energy level of the two functions. Ti is very reserved and sedate whereas Ne is much more active and constantly coming up with stuff. Granted, I get into swings where one is the default over the other, but I wouldn't say that they wrestle. There was a time not long ago where I was pretty guarded around others and my energy level was really low when I was in public, but I kind of realized that I was just coming off as unapproachable which wasn't really my intent. To fix that I just tried to act more personable (which I guess is more of an Fe thing, but I used my Ne to help my Fe out). You know, I'd maybe participate in conversations every now and then as opposed to constantly listening in, raise my eyebrows when others talked (it does wonders to at least look interested), and smile if the occasion calls for it.

I guess the extremes of each function being in control at any given time (in conversation, for this example) would be either a nonstop stream of babble (Ne being creative and just spouting off whatever comes to it) or stonefaced silence (Ti doing its thing). I've found a pretty good compromise between the two where I take whatever "witty" thing pops into my head and first kind of analyze it to make sure that I'm not about to say something completely idiotic, and then I may let it out, provided there's an opportune moment in the conversation to do so (Fe, again doing a little work).

I have this one thing I do that works both functions (I don't really know what to call it). If I'm just sitting around with nothing to do, or if I'm having trouble falling asleep or something, I'll just start imagining people/places. I'll just come up with everything in my head. For example, if it's a place I imagine what it looks like, it's layout, what kind of furniture is in there, etc. And I'll take that to whatever extreme I can, down to some really minute, useless details. All the while I'm coming up with the details (Ne) I'm making sure that they function within the environment I've created (Ti). So the details will have impacts on the place that are accurate of what you'd assume that particular detail may have.

Another thing I like to do is have little debates with a close friend of mine (who I'm pretty sure is also NeTi). We generally take common things (popular movies, etc.) and try to cast them in a new light (If you've ever watched After Hours on Cracked.com, it's a lot like that). It engages Ne by forcing us to generate ideas that we may not have had previously, and also Ti by making us work these new ideas into a cohesive argument (the other day we had a discussion about whether or not Sean Bean's character in National Treasure may actually be the "good guy").

I do try to make myself the "perfect" person (as perfect as I can), but I don't consciously attempt to find a perfect balance between Ti and Ne. I like to think they're both at pretty reasonable levels of use, at least in my head. And outwardly I can just kind of engage one or the other depending on the amount of energy needs to be moving out.
