Welcome

There are plenty of different toppers that will work on the eVic. Don't have one, but I believe you can use kanthal coils on this in VV/VW mode as well as Nickel or Titanium coils in TC mode. Plenty of pre-made/packaged coils if you aren't ready or don't want to learn to build your own.
I've toyed with getting one of these, but I just haven't rationalized it yet. I have plenty of other mods (non-TC) that I'm fiddling with.
MyVaporStore has the kit for about $56....
