I seem to be able to taste the rayon until I've run a ml or two through the wicks, is this the same for you?
after that though its frigging awesome! ..i hate changing my wicks so its ideal, i don't even change wick's for different flavour's, like you i have lots of mods but i've only run two for a while now, i do sweet, fruity, milk shakey and choc fudge brownie mostly which i find all mix well together on the transition

i try to keep it simple or else i get a headache with to much stuff, i just use two mod's and just change rda's from time to time, with the rda's i take off i pull the wick's and wash the rda with coils still installed then chuck em in a empty ice-cream container in case i want to go back to them, got to make sure they are dried properly though as some have rusted from the screws lol[/QUOTE]
I've had little to no break in time with my tanks (Aromamizer & Bellus) But my RDA's take a little longer, a ml or 2, same as you. My DIY lineup is all sweet flavors... Sour Apple Bubblegum, Jolly Rancher, Pineapple/Peach Cheesecake & etc... And like u, all my flavors are easy to transition thru should I forget which flavor I was using...lol My brother says I buy vape gear like a true woman, bcuz if I buy an atty, I have to buy a matching mod & vice versa...lol Same as when I buy clothes... If I buy an outfit, I have to get matching shoes, rii ??

Of course I do... I've been known to keep the same coils for months, in some of my setups & I have an old jar full of used coils, too..

I tried rayon for the 1st time a month or so ago. I know there was a lot of hype over it last year, but I had so much Japanese cotton I didn't see a need to try it, but a vapor buddy of mine kept saying how much better rayon is than cotton & he wasn't gonna leave me be, until I tried it.... Now, I liked it from the moment I vaped it in Bellus, but umm... yeah, I still haven't told him I ordered my own box yet...lol
