When I converted my parents to vaping I started them on DCTs with 18650 batts. After the struggles with being informed at the last minute, "We need more cartos", I decided to try their tastes with a tank system that uses rebuldable heads. I don't mind rebuilding the heads, and I kept them stocked with enough that when half were used, they could pass them along and I'd have a day or two to get them coiled/wicked. I ordered the X9 (Protank clone?) from Fusstech. My parents use an ungodly high menthol liquid that I DIY for them. *I order all their equipment, too. They're not interweb'd, being fogies and all. 
Anyway, the tops of both X9s cracked off and are useless. Luckily, they have cartos for the DCTs, but I'd like to get them a replacement that will use the stock of X9/protank heads they already have.
Mom requested something that had a removable top and bottom for cleaning purposes, as the X9 tank is attached to the top/mouthpiece.
I request something that has a tank that won't decomposed/become brittle enough to break from their menthol liquid.
I think it would be nice to have a removable driptip, and a high capacity (5ml) for extended periods between fills.
What suggestions do y'all have? I'm out of the loop as far as tanks and such, because I use homemade VV/VW bottomfeed boxes with RDA. I'm a mod builder.
