Right now I’m playing with Ceda-Serica. Because it came in a set of two I’m trying one with two small wicks CDN 2 and one with CDN 6. In my very limited experience, I’ve liked using two wicks on 3 inch diameter vessels because so far I get a nice sized flame (no soot or carbon build up), vessels have been staying relatively cool, great HT with a lower FO percentage (4-5% for this one), and still achieving full melt pool in the second half burn.
Since these tumblers came in a set of two, I’m also trying out one with a single CDN 6, just to see... because why not!
