I just hate jumping on anything with proprietary coils. Generally they cost more and can rarely find them local (especially where I am). Then of course there's always the, what if they discontinue them in the back of my head and such.
Now, knowing the players involved, it shouldn't be an issue here but you just never know, especially with the way things change. I've also been known to be cheap as well, lol. If I were going for high ohms like 1.6, to me it makes more sense to buy a carto tank.
Not knocking it, I like Phil, he's the one that got me to buy a Vapor Shark 30w back in the day, lol. He's a smart and super nice guy, so I'm sure they've worked out logistics on coils. I'll have to wait though and see how they pan out, I'd love another flavor atty that is more plug and play.
