I may be alone on this, but I'm getting damn sick and tired of my rebuildable stuff. Just hassle and more hassle to get a vape I don't even like. Then if I do get a good vape, I get sick of the flavor and the new flavors don't mix. I'm thinking about just trading/selling my kayfun and nemesis to get a provari with a pyrex tank. There will be no more hassle. So how do you think it will be going from kayfun to carto? Will the cartos taste really muted or what do you think?
