I actually like both the V2 Line and my Iatty ( a GG item ) but I use it as a dripping atty . For Genisis atty's , like the line and G_tank US , you need kanthal wire 32 , 34 , or 36 size , and some 400 size mesh , for the wick . You can purchase all of this on Ebay , fairly cheap . For the Iatty , you need both the kanthal , and some silver wirewire (non -conductive ) in maybe a 28 gauge , as well as some kind of wicking material . Probably have to get that from one of the vendors . You might also go look at Nhaler.com .They have a re-build able atty. forget the name , but should be easy to find . Not real attractive , in my opinion , but not badly priced , and they sell wick and wire kits for it , (real cheap )
