I can respond to some of your questions (from my point of view, of course), but not all.
Premium carts (what V4L now calls Wow cartos) are the lower resistance-type carto. They have a warmer vapor, and depending on your
vaping style, sometimes the cartos can get hot (I have burned my lip a little, when I was a new vaper.) Coolcarts are the higher resistance ones, and hold a little more juice. Some find the vaper to be cooler, and they don't burn out so fast at higher volt
vaping (such as using a PT.)
I think of premium carts as sort of the "regular", or "older school" carts, and there are many folks who have been
vaping a long time who prefer those. (Just as there are lots of folks who really like low resistance ones.)
I have only used the V4L ones, but I did not notice much (if any) difference in the draw between the two kinds. Some people think that the throat hit is stronger on the premium carts, too. Again, I can't say I have noticed a difference.
You might find this thread interesting:
Premiums vs. Cool Carts, although they are just discussing V4L products. I do know that the Turbos (from Vapor9?) and the Gold Label Deluxe cartomizers (from CigEasy) are equivalent to coolcarts, so I am assuming that the other cartos they sell are the premium/regular/lower resistance type ones. Bloog is going to be introducing some innovations in cartos, so you might want to check them out, too.
From what you have said, it sounds like you are a "Premium" kind of guy.
I Hope this was helpful. I wish all vendors would list the same information, so it would be easier to choose...if everyone listed ohms, then we would quickly learn what works best for our preferences, and be able to order without doing a ton of research!
