Personally I think we are only dealing with a language barrier here. Maybe even some misconception.
Let's try clear things up
Rayon is a material obtained from celulose through a certain process which varies according to the needs of the buyer.
Tencel, viscose, lyocell, rayon, cellucotton are all rayon fibers. Some are thinner, some are thicker, some are longer, some are shorter, some are compressed, some are "fluffy", some are strait, some are curly.
Obviously, some work better at sucking liquids than others. There are hundreds of different sources of rayon in common products. We are just starting to look for them and finding new ones every day.
O. B tampons for example is one of them
Now in my personal, subjective experience, tidi balls work better in my atty than Sally cellucotton. I actually felt a night and day difference. However, both are in fact rayon fibers.
You say fiberfreaks are superior. Maybe they are, I never tried those (they were out of stock at pink mule last time I ordered stuff) but even if they are so superb, that doesn't change the fact that it's rayon. The fiber may be more adequate to vaping, it might even be fantastic but... It's still rayon.
Finally, you said fiberfreaks doesn't burn. I bet it does, just like any rayon or cotton fiber. Make a video of you putting a dry fiberfreaks wick into a coil an fire the mod until the coil glows red and show us the fiberfreak wick won't burn.
There are many ways to pass a message. Being obnoxious, aggressive and rude doesn't help at all. Even if some people on this thread were considering FF to try out, I'm pretty sure you scared away half of them.
My two euro cents
