I have no polycarbonate tubed tanks, only pyrex and polypropylene. Well, that's not entirely true, just yet. I do have the Pro-V Cartomator SS like in your pic, which uses a polycarbonate tube. I have a blue pyrex tube ($15) made by Siam Mods and sold by Clouds of Vapor on its way as we speak that is supposed to fit the Pro-V tank.
As the previous posters have said, polycarbonate is vulnerable to cracking and/or melting by certain flavors of e-juice, notably cinnamon and citrus flavors. I've avoided products that use polycarb since I had a clearomizer melt in my hands after filling it with strawberry-lemonade e-juice. I also believe that all juices leach polycarbonate over time, but I can not prove it.
Polypropylene is said to be safe with the "harsh" flavors, and after using some of these juices in polypro tanks, I've not had any issues. I firmly believe pyrex glass is the way to go and will have a much larger presence in the vaping community if the e-cig manufacturers listen to their customers. Pyrex is a superior and totally inert substance that will not react adversely with e-juices.

As I mentioned above, I do have the
Pro-V tank. It's certainly a well made tank, it's only short-coming being that it uses a polycarb tube. I'd been on a search for a pyrex tube that would fit it and ECF buddy
chohan confirmed in his post here
http://www.e-cigarette-forum.com/forum/tanks/314551-quest-glass-pyrex-tanks-27.html that the Siam Mods pyrex tubes will indeed fit. COV has clear, blue sapphire, and green pyrex tubes for sale.

I've been trying to find info on the
Cirrus tanks for a couple of months now. From what I have been able to find out is that they are made and sold only by a few local vapeshops in California. They have the beginnings of a website that was not yet working the last time I checked. I really like the looks of these tanks. Not sure of the endcap material used, but allegedly the tubes are available in polycarbonate or pyrex. I heard rumors that these were being sold for as much as $75, which seems pretty steep, but I have not been able to confirm any prices.

A Pro-V cartomator with a $15 Siam Mods pyrex tube from COV might be possibly competitive price-wise with a pyrex Cirrus tank, so the choice would be which one do you think would look best on your Provari mini? It looks like the Cirrus tanks should be available in your neck of the woods.
If the original poster has any details on the Cirrus tanks, please share. Should you get the Cirrus tank, we all expect a complete review.
