Have you tried using any Cartomizers yet? I mean using ones that you fill yourself. I have gone to the Boge (which I sell on my site) and have really enjoyed the flavor difference now. I have gotten myself hooked on DIY and also found that everyone that I get started on it, is just as enthused about it. It makes a difference when you control your own flavoring and nic levels. I have actually gotten myself down to 0-8mg nic levels by doing my own flavors and no problems at all.
The cool thing about the ego kits is the versatility. You can drip with them, use the carto's or tanks. I also seen how some are starting to mod them. I have not tried any of the boosters they are now sellign for them, but I did finally get myself a few variable voltage mods and really loving them. I still carry my ego battery with a LR carto, but the difference is in the flavor production for me.
Yes, I occasionally try cartos, and I REALLY REALLY prefer the "b" ego-t tank. I've got an ego mega dc and 3 smoktech 1.5 lr dc clear cartos on the desk right now as a matter of fact...sitting idle. My 'b' tank has better VTF, and doesn't snap/crackle/pop, which I cannot stand. Its a chalkboard scratching thing to me, especially when the pop happens as I'm inhaling.
When I want to try something new, or change up, I drip, using a standard 510 atty, but for normal vaping I'm still loving the ego-t "b" LR tank system. I HAVE purchased some kgo 1100mah bats which give me a slightly warmer vape than the standard ego bats. (4.0 volt on the kgo vs. 3.4'ish volts on the egos).
