I like cartos a lot. I can usually get them working well with very good flavor. Once in a while though you come across a bad one. I assume it's something in the manufacturing process.
One of the keys is finding a good supplier so that you have some sort of baseline expectation of quality. Rather than a vendor who just buys them wherever has the lowest price that week. That way you end up getting a lot more good than bad.
I do have to say though that the Evods have been winning me over lately. I like the T3S's because they hold more juice, however I seem to get much more and consistently better flavor from the smaller Evods. I'm thinking it's gotta be the heads.
But for some more subtle or complex juices, the cartos still come through better for me.
Just ordered some of the new Aspire Clearo / Glassomizers to try because they're BDC vs BCC (bottom dual coil vs single). I've heard rave
reviews about them and I do love my dual coils (when it comes to cartos) and I love the bottom coils (when it comes to clearos).
They come in a bunch of different styles. Large & small tanks, plastic clearomizers with & without the ego skirt threading, and a pyrex glassomizer version. But they all use the exact same identical dual coil head. Other than the head they work just like Evods or Protanks.
I ordered the 2 of the pyrex glass ones with the ego threading and 2 boxes of heads.
Oh Trav, you're just like me ... you have waaaay too much time on your hands!
