I have a Toptank Mini and want to get a back-up mini RBA Head.

Im confused as I don't see a sku that says top tank mini rba on here….its just sub tank rba…and the V1, V2 makes it tough for me.

Is it true that Kanger only puts out one kind of rba head now…with the smaller holes?

And these are designed to fit both sub tank and top tank minis?
