I have never used a carto, so what you just said was greek to me, but I think I understand, I just really like the look, of this style of tank. The ones you have and others out there, but I want to be able to rebuild the thing, If they all look nice and pretty, but I am locked into buying these cartos, to use it them, I don't want it. I just saw a review of a new tank by leo, called the sophia? Something like that wound be great, but I want American if possible.
Our tanks will work with a Diver. For refilling you just have to refill like your typical carto style.
When we need to make another run of tank caps we plant to mill out the area for the Diver flange. So it will sit flush along with DCT cartos. That is the only downside to Diver flanged models.
