When I was using the Cleto tank with coils at 0.15 I found it hard to get a satisfying vape below 40 watts, and 40 was really pushing it. I think it would be hard to get those coils vaping well in your current wattage range.
You could certainly try it, and if it doesn't go well use the RBA deck, although IMO, if you go that route, you might better be served with just buying an RTA that's easy operation with even a single build deck, that has the reputation for good clouds and flavor, I say this only because I feel that using a tank designed for coils you build yourself tends to be easier than an included RTA or RBA deck--- the tanks aren't exactly designed for that, and often the build deck is pretty small as it's sort of "retrofitted" if that makes sense, to the tank that's pretty much been designed for drop in coils. If you like what you are using now for drop-ins, that makes a lot more sense to me, might want to take a look at the RTA/RBA section of the forum, to see what's out there, how people are liking it, and how the RTA performs....
Just my opinion of course, but I found that those really low resistance setups do require higher power levels to perform usefully. They also tend to blow through juice, which may or may not be an issue for you.
