The anti spitback design is probably for those that want to vape at lower watts, this is the only time I have gotten spitback, you have to crank the Crown up which is probably what most do.
What I would really like is SS coils that actually work with SS TC, the Crown is the only ones that doesn't and it has something to do with using Ni tails or something like that.
The new tank looks like a more dressed up version, on the fence, ahhhh, who am I kidding, I will probably buy one
Vape Royalty (the link is to there site in the OP) is a solid vendor too. I recently got a mfg defective Mutank from them but there customer service was great and replaced it. There my go to vendor from now on due to competitive pricing and great customer service. @
