Thanks Kent! Yes, that answers my questions and then some. I also thin my VG juices with water, as just VG is too thick. Mine is a Greensmoke, not greencig, but they are probably similar enough that its the same idea. My main question was inject to the side, or the center, or let pool, and you state what I suspected. And yes, with the GS cartos, their base flavor leaves a lot to be desired, although vanilla and menthol were ok. Their tobacco was not great at all. Might try to find empty E9 cartos at some point.
For now I'm mainly using a 510...although I am eying the Bart with much interest. You still like yours? And what do you think of the tornado? Rather OT for the thread, but those two are catching my attention these days, and I want a PT that is good and reliable, thus the Bart seems like a good fit.
Ah, greensmoke - one I haven't tried ;-) The greencigs are a bit longer than the others I've tried.
Bart - I stilll like every one of mine ;-) I've had a dozen come through me and I tested each and each are consistent in quality and performance. That's no guarantee but it might be helpful to know. I have a Protege which is really nice too but at home the Bart looks like an appendage.
Still testing the Tornado - I can say that the first full charge lasted from 5pm to 11:35pm and I tried to stay off other stuff for that period of time, so moderate to heavy vaping, I'd say. There doesn't seem to be that 'peak volt' like the 14500 but it seems better than a mega and lasts about 2 1/2 hours before I noticed a bit of a performance drop - really isn't bad - good actually. And like some others, that last 15 minutes gets weaker before gone. Although the 14500 seems good until it quits. Vapor on the tornado is between a Janty stick and the 14500, like a fresh mega perhaps - sufficient for out and about, I'd say.
I didn't get the kit - only two batts, one cone and one charger adapter and I'm charging it right now @2am and it's still red. I know the actual charger is supposed to be quicker - so nothing to judge that by other than other stuff like megas, and regular batts, and they'd be done by now on the 5 batt TW charger.
Ergonomically, it is good. Nice button - wide enough not to be 'pointy' but small enough for the unit. With medium sized hands and using my forefinger for the button, my pinky is 'in front' of the batt and three fingers covers the whole batt below the cone, fingers closed. I'm letting the wife use the cone - I was hitting it on vaping and it stops airflow if you cover it. I might have to use a mega atty and cart on it.

I put a 901 on it and that worked fine and a cartomizer - also fine. And those, by using an adapter from HG and that brought it out of the cone a bit further. I'm using a flat tip 0 style which is a tad longer than the D style so the D 901 style may come up short for some. (that is without an adapter and using it on the reg. 510 atty).
Good looking unit even without the cone but that does have a more aethetic look of course - it's all in 'transitions' ;-) seemless and all of that. lol. Without, it looks more techy. But not tacky.
It may very well be a good starter kit for someone who isn't tethered to the idea of a cig look-a-like, but would still like a tube style, cyclindrical looking device rather than a box mod. It produces more vapor than anything less than the Protege/Chameleon. But anyone wanting
biggest vapor would have to go for a 14500/510 or a 5volt/901 combo, etc. imho....
