304ss was what i was thinking of going with after using the Crown coils, it took the power really well, though at 100w your battery life is going to suffer badly lol
The one thing that temps me to SS is the flavour, NI200 gives me a horrible chemical taste if i push too hard, Titanuim tastes a bit odd on fresh coils for at least a dozen puffs till it settles and then its grand, Stainless Steel seems clean from the start...
Are your coils spaced or contact Rilot?
Spaced.
