If this is his first rodeo with rda's it might be best to use Kanthal instead of SS.
OP, my preferred coil in the Griffin due to the tight deck was a 24 gauge Kanthal wrapped 6 times around a 2.5mm bit. It would usually come out to around .30 ohms. 40-50 watts would be sufficient.
The main thing is it's a starting point for you.
The Zelos won't fire any thing lower than .5 ohm, and I'm not sure what the istick will fire as it's an old school mod.
Did you have the 25mm Griffin or the 22mm?
I'm going to give the OP enough brains to have bought the 22mm tank, and if so I can't even imagine 24 gauge dual coils fitting and even if they did the mods wouldn't fire it..
Also, he needs SS for TC, he may as well get through the learning curve for stainless now.
I agree that he needs Kanthal for the Griffin though...
