Sorry that no one got this quicker! Let me help how I can -
Yes you can put your tank on top of that mod. Be aware, in my experience mechanical mods (which is the mod you are looking at getting) are unregulated, so you will get results which will vary as far as cloud production. Besides that, I've used both RDA's and Tank systems on mechanical mods with no difficulty.
Fasttech is a company which is reliable, to the best of my knowledge and should be able to get you what you need.
Now, you said you used your friends and got good cloud production? Some of that could be e-liquid (vg to pg ratio), Ohm and surface area of the coil. Not that I am suggesting not to get the FUhatten, but simply that you need to be aware of all of factors, in case it helps you make a better choice.
Good luck!
