Oh wow, a US citizen that uses degrees in Celsius, you don't see that very often
My most used and fav overall temp is 215C (that's 420F for those too lazy to convert

) in Temp Ti mode on a Evic VT. I mention this in detail because I've read that the VT usually reads a little higher temp on the screen than it really is putting out in temp ti mode (it's my only mod so I have nothing to compare it to).
But it varies for me. I can go anywhere from 185 to 235 roughly, depending on my mood & juice. Beyond that it gets too hot for my taste. Usually I'm at 210 to 220 though.
