Hi again Robin! lol.. Just left you a hello in your intro thread.
It sounds like you are looking for more vapor than your present setup allows for. For maximum flavor and vapor in a tank, I can't recommend the Uwell Crown highly enough. But the power requirements are more than your spinners will probably handle.
The form factor of the spinner is somewhat limiting regarding choice. If you think you can tolerate a slightly larger device, your options become immense. Moving into the world of replaceable 18xxx (350, 490 and 650 lengths, all 18mm dia.) batteries will not only allow you to have numerous spare battery cells much more cheaply (about $5 each) but also allow you to upgrade devices as the tech changes and still use those same batteries.
I would highly recommend the Evic VTC Mini or Cloupor Mini+ for single cell 18650 batteries. They can achieve much higher wattages than your spinners, and also support the latest Temperature Control devices. It is a LOT to learn, but they also function well as traditional watt mode devices until you get a handle on the latest tech. You will need batteries (I recommend the LG HG2's), and a charger (The Xtar VC4 is sweet). You will likely get a LOT of recommendations, but those are my present favorites to recommend to a new vaper who wants equipment they can use now, and also grow into.
