Joining the discussion late I see.
Whoever commented about a cartotank having and retaining the flavor/taste of a freshly filled new carto is pretty much correct, IMO. The issue of using cartos solo is you can't see the level of the juice as you vape, so unless you are OCD about topping them off frequently, you'll eventually run into dry hits or a burnt flavor. Once a carto has that burnt taste, it's ruined.
A carto in a cartotank is continuously fed juice from the tank as you vape. It keeps the carto fresh and prolongs its usefulness.
Not all cartos are created equal. This why cartotank users who can get them use Ikenvape cartomizers. These are a premium carto made to the specific standards by Isacc at Ikenvape. If you ever wondered what an American-made carto would taste like, it would be an Ikenvape carto. Unfortunately for him and everyone else, his manufacturer in China won't make them in the numbers that he can sell them. So, they are often out-of-stock.

My suggestion is to get on the "notify me" email list and when you get the notification they're in, purchase as many as he allows; usually a 25 count limit for each type. I usually order 25 each of the 510 Fusion and Platinum when they're in. Don't procrastinate, they will sell out in a matter of hours.
The ultimate enjoyment of a cartomizer, the same as any other juice delivery device, depends upon using the proper resistance or ohm for the voltage that you are vaping. If I only had the low resistance dual coils that were my first cartomizers to judge from, I likely would have given up on cartos myself. I prefer single coils, and I prefer a cooler vape, so I used standard resistance on my unregulated PVs and use 2.5 - 3.0 ohm resistance cartos on my regulated PVs.
Back to the OP. Since you enjoy clearomizers, have you tried any of the clearotanks available? Top coil varieties for a warmer vape include the Vivi Nova and Kanger T2. Bottom coil varieties for a cooler vape include the Kanger T3, Evods, and Protanks. Some of these require the eGo adaptor to fit a 510 center pin. I've only used the Protank, which has a 510 connector.
I've yet to try a Killer or Diver in a tank yet, but one is probably on my long list to try in the distant future. I'm having too much "fun" with my AGA-T2s and bottom feeder mod for anything else new.
