Smok coils are much more and tighter packed than other brands, hence they burn out quicker too and need special preparation when breaking them in.
The recommended wattage on those are never accurate either. But different coils and tanks will perform differently, you'll have to play around with it and find a wattage or temp setting you personally enjoy, not what smok or cleito or any other manufacturer tells you. Its a good guide line but that's about it. I've used in the past a ceramic tank, its recommendation was 40-60 watts, this thing wouldn't even get hot with that recommendation. Had to put it on 80 before it slightly produced vape, at the end ran it at 90-100.
Now you can't do that with the smok or you going to replace the coil every 3 hrs, however you get the point I'm trying to make lol.
For now using different tanks on your mod is fine, but I would recommend getting a backup. Out of experience I know that switching tanks every 5 minutes on a smok mod will lead to issues. The 510 isn't greatly made in these mods, nor is the chip. So keep that in mind, maybe stick with switching every day or so.
