Hmmmm. That's wierd. We have the same mod and different opinions on this. I actually did 2 316l builds to test this out. As far as I can tell the temp of the vapor and performance in general on the mods part is the same.
Both are 3x 26g 316l cores with different wraps. The flavor and vapor density is different but temp feels right. I've been doing 316l TC builds on this thing since I got it and 500 degrees feels the same on any build.
Either way, in power mode it's ok to cantact so long as you fire out the hot spots.
Even spaced coils will act funky from time to time if the spacing is off a little and still need to be pulsed and tweaked.
I think what I'm trying to say is it's fine either way just make sure they heat evenly or the load will bounce in addition to a subpar vape.
