Posted this another thread but it got buried... ATM I use the old school 401s for my flavor testing and have 1 atty for each flavor. Now that I'm running low on them and find the flavor is definitely sub par to a RBA SS mesh wick tank, I'm looking for a good RDA that I can use a SS mesh wick. Looking at: Smokteck 510 RDA (not showing wick type) IGO-L 510 RDA (shows Fiberglass or Silica Rope wick type) IGO-W RDA (shows Fiberglass, Silica Rope or SS Mesh wick type) Phoenix
