I would recommend a Protank or Evod. Cartotanks can be quite finicky if you aren't familiar with them. Would hate to point you towards something you aren't prepared for.
Ironically, I could easily say exactly just the opposite of that in my experience. I've found in general common clearomizers to in fact be very finicky when compared against cartotanks. This just demonstrates perfectly that we all prefer one delivery
device over another based on our own personal experiences.
Granted, my experience with clearomizers has been limited to the top coil variety. The Kanger ProTank and Evods are bottom coil and I've yet to use those, so perhaps my reservation for clearomizers should be qualified. The Vision standard clearomizer and Kanger T3's were on the harsh vapor side of things for me, yet I'm fully aware there are vapors who prefer those over another device.
My preference for almost a year have been pyrex cartotanks. One only needs to view my photo gallery here
http://www.e-cigarette-forum.com/forum/members/baditude-albums-pictures-my-setup.html to see that. Cartotanks do have a slight learning curve, yet I believe they are worth a trial. Follow a good accepted method of setting them up and you should have no issues.

Clearomizers and clearo tanks use string wicks which must be kept saturated with juice or they will give dry hits. This means they are position dependent and must be frequently tipped or tilted or the juice swirled, which I find annoying. The string wicks often mute some flavors (my experience).
The polyfill of a cartomizer completely surrounds and bathes the heating coil, which ensures more juice and more flavor to the heating coil. A cartomizer or cartotank is not position dependent. Aside from the one clearomizer that uses pyrex (ProTank), the others still use polycarbonate plastic which can crack or melt when used with many common flavors of juice.

The choices in common juice delivery devices are many
