On the advice of this thread I reduced my "stuffing" in the coil
Likewise, I did that same a little at a time over the course of a few months. With each wicking I pulled minutely less and less into the coil until I noticed a marked decrease in wick longevity, wetness of the vapor(increase in dry-ish hits), reduction in vapor production or reduction in flavor. Interestingly all four of those symptoms of under wicking happened at or near the same level of under wicking. Not only that but at some point of under wicking the rayon taste may never go away. Guess where that point is? Yep, when it stops squeaking!
Next I began increasing the amount of wicking until the symptoms went away and then continued wicking heavier until those same symptoms began to reappear. Interesting here was that the symptoms of over wicking came on much slower as I wicked heavier.
In the end the experiment proved three things to me:
1. Rayon has a narrower window of acceptable wicking density than my experience with cotton.
2. It is better to be leaning towards over wicking than under wicking with Rayon. By doing this it gives me a wider window of acceptable wick density so I have a better chance of having a good vape, even if not spot on.
3. The most important:
"If it ain't Squeak'n it ain't Peak'n"!
