Welcome, DedTV!
You've some interesting posts, thank you.
You're absolutely right about "tobacco-y" flavors. I hated them, from every brand I'd tried, from just about the start. The only ones I do like are the ones I'd never had before or have flavors leaning to other areas. 555 is my favorite tobacco flavor, smooth and slightly nutty, followed by RY4. I vape menthols flavors, whereas I hated menthol cigarettes. And I like most everything clove, but didn't care for clove cigarettes. I don't care for most sweet flavors, but I have found that I really, really like watermelon and pear flavors. And I like just about everything with that "cool hit" that ECBlendflavors.com offers. So yeah, don't stock up on tobacco flavors, but stay ready to try more flavors. SI prefilled carts are the best of any. So are their blanks, I think. Liquids I get mostly from ECBlendflavors, but SI's 555 can't be beat.
I, too, find the X2 to be an excellent battery, though I still use my 78's. I was taking my X2 to work, but I find I think I'd like to keep it at home next to the computer, and take my 78's to work, along with the Mega PCC. I now use the cart cases for most of my spare carts, and they are easy to label with what is in them. The 78's are more compact for work, and the loaner kits I have to offer at work use 65's. I want things to be a little more familiar looking to those who really want to give it a try without commitment. I use the sealed automatic batteries, mostly, but I do have a few manuals mixed in. I did order a backup X2 in manual, but it too will stay at home.
One thing I don't like about manuals is that I can accidentally get them switched on if I don't carry or store them properly.
