I think I can taste silica, wick in clearos, more than polyfill. I just started using cotton in my RBAs because of that. I wouldn't compare a prefilled cartridge to a cartomizer. Prefilled cartos are crap.
Until you get a protank or non-polycarbonate tank, be mindful of the flavors. Just don't use cinnamon or heavy citrus stuff.
