I can say for a fact, much like I posted a couple times. Rayon, head to head with Cotton has won almost every battle. Most recent with a Heron. I can not get over the wicking.
I told Yanks last night, my rayon Heron build at 1.0 I originally filled the tank with 4.0 ml on 2.5 inches of fluff. 2nd tank I filled 3.6ish and I could of put in a slight bit more.
Rayon wicking is phenomenal and fast.
Remember unlike cotton have a little wick resistance in coil as the rayon will contract a slight bit.
