I use GP Spheroids (have 3 of them) for my daily
vaping. Silica works, in my opinion, great with them if you do a "lasso" wick. I have never had an issue with them and have not been happy with cotton on the Spheroids. Cotton works, and I'm sure I could play with it enough to get something I love as much a silica, but at this point I am happy to use silica. I do use cotton to drip on my Quasar. It holds a ton, but it never struct me as better or worse in the taste department. I figure whatever works for you, go for it. Just like tools, there are some that work better for some people doing the same task as other people.
