For your 3.3s, you may want to look at LR cartos - dual or single coils. I like the Boge 2.0s on my kGo, and SmokTech 1.7 single coils - but, the kgo is 3.7, so it may be different - I don't think I have any 1.7s right now, but I do have a boge 2.0 that's I filled for Iron Monkey to sample Dragon's Tear - I just popped it on the LT & dropped my voltage to 3.3 - it's a little cool for me, but has great vapor production at 50/50 and decent flavor. I've been using a LR DCT (smokTech), dropped it down to 3.3, again, a little cool for my tastes, but the vapor production is great, and the flavor is decent but muted compared to even 3.7.
From Luvinit's post, it sounds like you may want to try a stardust/vision at 3.3 (trying now....) Not bad! Better flavor than the Boge or ST I just tried, but the vapor production is reduced lol I think you're going to wind up with some trade offs when your V is only 3.3.
I have the LR Stardusts on them now, and the flavor is good but, like you said, the vapor production is a bit weak at times, and they can be a bit finicky about temperature changes. I don't mind cooler vapor when I'm out and about, so I'll give the Boge 2.0 cartos a try. How about a tip for the cartos (drip tip, or something else)?
Nope, Glen probably doesn't qualify as the voice of reason considering he just bought a VV too
I haven't really figured out how to keep it all sorted either - I know with atty is which, and if I pop a carto on a device and take a puff, I can generally figure out the flavor, but I'm serious considering buying some little colored round stickers, using a specific color for each resistance, and coding the bottles with numbers (corresponding # goes on little round sticker) - may or may not work!
Who me? I'm absolutely the voice of reason... I always find good reasons to buy stuff.

Like, what are you talking about? Like, I still, like talk like that....like totally radical!
Whoa! Dudette! That was like totally unexpected and supremely rad! I think it's time to load up the van and cruise the strip! (Yes, I grew up on the Jersey shore, and no, it was nothing link the TV show.)
