Considering these wicks last a good amount of time what is your guys experience with changing flavors on the same wick with rayon? Do I have to completely rewick or is it good to go the way it is?
It all depends on the flavor, mints and some fruits and a lot of the syrupy commercial juices stick like glue and linger almost forever never really going away. They even linger after a thorough cleaning. All my DIY tobacs and other mixes go together so I if lazy overcomes me enough not to refill a jug then just put another flavor into the atty then within several vapes the new flavor has taken over.
My coil has to be completely spent before I do a rewick or rebuild, no more do I sit down just to change wicking to another flavor.
I noticed you used the word "trim". Don't confuse trim with thinning the tails, they are 2 different processes. Thinning the tail is what promotes the juice flow with rayon, too bulky chokes, too much thinning it could leak. The only trimming I do is after I've thinned the tail I make a flower as you can say then trim off the bottom 1/4 to 1/3 that IMO isn't needed then juice the wicking and trim to the length I want.
