They've come out with all the locking systems because some of the production tanks (smoktech) were Super loose.
tanks like IBT, Phiniac, and such aftermarket are made much better.
Carto-tanks are Very popular, but you don't see as many posts on forums about them because they Simply Work.
Clearo posts are more frequent because of all the problems and because they've been forever coming out with new ones that are Supposed to work well.
I rebuild my clearo heads, but the $$$$ investment to switch to RBA's is beyond my pocketbook, and I really don't want to get into it. A dollar apiece for cartos, given how long they last, is not bad at all.However, once they quit smoking and become frustrated with the issues of clearomizers, they are willing to put in a little more effort to continue vaping without needing to step up to rebuildables...which is another step up altogether.
Maybe you should move on to Clearomzers, Tank & head in one package?
Carto tanks are just about dead. There are better devices available these days.
I totally agree with this. B&M shops don't sell a variety of cartotanks because once they sell a cartotank they don't make any more money on them. They don't make any money on replacement cartomizers.
Vendors make money on clearomizers because they are geared towards novice vapors just starting out. They are easy to fill and easy to replace the coil heads. They make money on the replacement clearo heads, and also usually end up selling another clearomizer model/brand because the original one gave burnt/dry hits, flooded, got juice in the mouth or leaked all over their battery.
Cartotanks aren't offered to novice vapors because there are multiple steps involved in setting one up which would look too complicated to a new vaper. Most newcomers would say that's too much work. However, once they quit smoking and become frustrated with the issues of clearomizers, they are willing to put in a little more effort to continue vaping without needing to step up to rebuildables...which looks even more complicated than a cartotank to them.

I store my unused cartos in unflavored juice, so they are primed already.
Your tank spins around the carto because its o-rings are of inferior quality. Instead of putting better o-rings in their tank, the manufacturer decides to use a unneccesarily more complicated solution by using that fixation screw.When I attempt to unscrew the X8 tank without the thumbscrew attached to the carto, the tank simply spins around the carto.
Could it simply be that a better tank would fasten itself more tightly to the carto, allowing me to do swap tanks without the screw?
I don't use a flanged carto or locking tank for the same reason. The O-rings on IBTanked are a little loose immediately after refilling but as the O-rings squeeze out liquid from between the rings and the carto the grip increases a lot. I pocket carry my rig all of the time without leaks or spills..In the three years that I have had my J-Tanks, I have never had one slip off. In fact after a carto has been in one for a few minutes, I need to press the connector end of the carto against something (edge of my desk) to get it to move. There is no need of flanges or set screws, all it takes is a proper o-ring fit.

I would like to recommend the Boge F16 V2 carto tank. It is a 5 ml glass tank surrounded with an cage which comes in different colors. It also comes with a fill tool that can be used as a drip tip. You can get either the Boge xl cartos with the regular flange or the ones made for the F16 which have a different type of flange. The flanges lock into the bottom of the tank with a twist. I own a couple of these and they work well and are priced very low. Just my opinion but worth a look at.
... I am sorry to differ but often my 25mm IBtanked with unflanged cartos is hard to remove. It is even worst if my PV has a larger diameter like my 26650 mods.
The carto slips and it takes a little care not to pull out or push in the carto (if without flange) from/in the tank. This is less likely to happen with a flanged carto as it has more contact area and I can press on it without the risk of pushing the carto in with the resulting mess. I am now carefull not to screw the tank too hard on my PV when I use an unflanged carto.
For vaping quality, I am very happy with my carto tanks.
