I still bought the PuriTank. I believe the holes on the base are the same as the ProTank 1 which will still make it airy. The PuriTank has 2 holes only and I have tried it. Vapes great. The only plus I see from the ProTank 2 is that it will be easier to clean since you can remove the glass cylinder. Other than that I don't see it being better than the PuriTank.
Considering you are in Orlando you can visit Esmokeronline, they have 2 locations and they have the PuriTank in stock.
