Heyas Arcticchill360,
The great thing about vv is that you can use such a wide range of atties/cartos on it. I use cartos except to drip and try new flavors. But, you should be just fine with anything in the 2.0Ω - 4.0Ω range. Anything lower than 2Ω will probably still work. Just be sure to set the voltage on your lt to min (3.0v) and work your way up if you're using low Ω stuff. Anything over 4.0Ω and you may not get enough warmth/vapor/taste. That still leaves almost anything made that will work well with the lt. I have some lr bridgeless atties that I bought that are too hot even on an ego. Might give them a go at 3v and see if they work. Otherwise I've pretty much written those off as a bad investment. I've tried a 4.5Ω carto at 6v and found it was underpowered. Fortunately only ordered 2 of those. Another thing to toss in the sock drawer for possible future use
After amassing a huge stockpile of cartos/atties trying to find the best setup for my ego before buying a vv, then trying all of them on vv devices, I've found that my favorite for vv is just a plain old boge sr carto (2.8Ω - 3.0Ω). They're inexpensive, readily available from most anyplace that sells cartos, and they just plain work well. Also, the lt comes with a 3.5Ω atty if you ordered the kit. Always good to have a spare or two around, but if you're already
vaping, pretty much anything you have on hand will be usable just by adjusting the voltage on the lt.

Edit: I should have noted that the above was assuming a single coil carto/atty. Dual coil, probably something less than 2.5Ω would be best.
