The carto like sleaze I the aspire heads doesn't wick. It might if you use 100% pg. but fails hard with 50/50
I have a PT3, got it yesterday. Aspire should arrive tomorrow, so i can give you a comparison then.
So far, not a fan of the PT3. I like that its glass, solid construction, big capacity. I *dont* like the ultra airy draw!!! I mean, its like breathing through a 1/2" straw. Too airy- makes the hits cool and weak. Ive tightened the beauty ring up and restricted airflow as much as possible by that method, better but still sucks to me.
Vapor production is just OK- no better than my trusty ol' EVOD (which i like better, actually).
I've had zero issues with my aspire bdc vivi nova pyrex tank. Been using the same head for nearly three weeks. I'm not sure why some people are having problems.

OK in follow up to my above post- I got the BDC today. Head and shoulders beats the PT3. The PT3 is more sturdy/solid, made of heavier material/glass. But- the vapor, flavor, draw of the BDC just blows away the PT3.
The PT3 is usable and Ill probably use it here and there. But no contest- BDC wins!
I've found the same thing with the Aspire, inconsistent heads. Some are really good and some are really bad. From what I've read you probably need an airflow controller with the Aspire. But then I don't think that would do anything for the inconsistent heads.
Haven't tried the PT3 yet. Right now I still prefer my PT2s and carto tanks.
