When you say for review, do you mean a review that you would post on here? Or just review for your own views about it? I just fill a tank up, and see if I like it. I’d only change the cotton if it needed changed anyway.
I would use a simple coil in just one of your prefered devices and get to know what you can achieve from that. Then you can recoil and wick for every new juice so you get consistency and see how the different flavours perform. You have a base from which to start from. You can then move on to different tanks/rda ect. But you need a consistent base to start for all things to be equal.
There is no point in reviewing a juice with different tanks on different coils. Juice reviewing is time consuming and I would think bloody hard work. I give respect to all the juice reviewers who take their time and get consistent results.
When I am testing juices I use a dripper with a clean wick. I find that if the juice is good for dl then its generally good for mtl. A good mtl juice is frequently not so good for dl. IMHO.
