Welpie, I'm one of many setups as well (18 at the moment). I tend to do what most vapers would NOT choose to do, and that's keeping a spreadsheet.
I'm so boring.
Hey, I have spreadsheets for almost everything, business and personal. But I just can't do that, Kat!

I used to only have 2-3 setups. But now, I'm trying to pare it down. I have 2 of my NET tanks- one on my favorite hitting mod, and a secondary one. I rotate those tanks when one gets old and is nearing rebuild time. And another one with unflavored. And currently 4 pods lying around.
But I am going to retire a few of the pods- they're just not good enough to buy replacements for all of them. I'll probably keep on with the 2 tobacco/1 unflavored rta's, and a single pod. I just like changing it up throughout the day, to keep my taste buds/throat guessing. But I
am tired of my desk being cluttered with it all. It got worse when I started with the pods, and making salt juices specifically for them.
