I don't think this setup would satisfy my mod whomping at all. Even though I still use my GS tanks I'm finding that I use my 40W istick more than the 30W's I have. With the 40, I can throw an STM running a Ni or Ti coil on it at 400 degrees or a .7 or.8 Kanthal coil and run it up to 30-35W. I would like to try the .75 coils though.
