I'm wondering if anyone has ever used anything other than SS mesh as a wick on an RSST. I've been using it for several months now (500) with 28 - 30 guage Kanthal, and while I've gotten pretty darn good at making the wicks and coils, I've never felt really satisfied. I seem to get a metallic taste - which would stand to reason I guess. Just wondering if there might be another way, say ekowool or silica? Appreciate any input, maybe it's just time to move on to another rebuildable.
