Or a lot of times the cotton can collapse and what your getting is a dry burn hit. Coil drying out cotton not burned because its not contacting the coil to wick to it. The part that has no contact dry burns. Now that's horrendous.

Silica present in natural sand wont have the same effect on lungs as silica fibre. I know that when wet its unlikely that any of these fibres will come out of it, but I must say that silica can "burn" and give off foul dry hits. Or at least it can become so charred that you can taste it. This is certainly true in cartomizers that fail to wick properly.
The juice I use is at least 80%-85% PG, because with my asthma, I can't handle much VG at all, it's too heavy, gives me an awful feeling in my chest. So my juice is quite thin, and I have to use a pretty considerable flavor wick, no matter the material. To me, cotton just burns at far too low a temp to make it really viable for the high wattage I like to use, with the thin juice I use that demands such a flavor wick. It takes a lot more heat than these PV's can generate to really burn silica, so if you get any burnt taste, it's gotta be the juice.

I've tasted that in a carto that I used for too long, and it really is nasty, but I think it's "polyfill" that gets burned, and that's polyester, god help us, a petrochemically-derived polymer. As much as I like cartos for convenience, that thought of inhaling vaporized polyester is always there in my mind when I'm using one. Really I think silica is by far the best choice; as you say, most unlikely for it to shed fibers when wet, and when well maintained -- obviously it's not immortal, you have to replace it on a regular basis, and take care with dry-burning it, but it's so much more hardy than cotton, and so much more resistant to heat!

I stopped using silica because of dry hits. Because it can't keep up with chain vaping or higher power. The dry hits taste pretty bad on silica. And yes it is juice burning because the coils dry and it's starting to dry burn. Cotton wicks much faster when used Properly. When used properly it is, and juice tastes better, than silica.
Andria I thought the same at first but then I finally got cotton down and never went back to the 40 ft Of silica I had just bought. But silica has its place, and advantages, for moderate or mid wattage vapers.
If it cotton burns easily or tastes like cotton your using too much, too dense, too tight.

It seems that to tight or to loose is just as much an issue as to much or not enough - and that seems very dependent on your juice and how you toke.
IMO, the cotton wick's tightness/looseness/density (same thing?) has more effect as the wick goes dry. If you drip often enough, the precise tightness won't have much of a difference. Of course, the tighter the wick, the slower the wicking, and the sooner it will go dry (inside the coil).
This is true. The "butter zone" is a kind of tight in the coil and loose-ish outside of the coil kind of in the well area of the dripper.
Exactly why I stopped wasting time with sub-ohm cotton coils trying to use wicks running inside of them. Wrap the outside of the coil with cotton instead. Far more surface area and far more cotton to transport liquid
I havent noticed this at all personally. rewick my RBA all the time with Organic cotton right out of the bag and all I taste is the juice
Ya me too, when I try outside-the-coil wicks I dont get nearly as much flavor, heat, or vapor density.
I use cvs sterile 100% rolled cotton, it wicks the best for me. No cotton taste now that I learned (the hard way) how dense my wicks need to be. This roll will probably last me a lifetime.
I use organic cotton balls from London Drugs, my reasoning is that "sterile cotton" products may be germ free, but they still will have gone through all the pesticides
