OK, the mesh thing has piqued my interest and have ordered a Origen V2 from FT. Clone thing I guess, but hey ho. I have cleared a direct path to the back of the garden, should defenestration be the end result, Jonny Wilkinson style. But a few questions; What is a topper? What can be used for wicking? Is the mesh reasonable wick as standalone? What sort of Ohms/Watts should be used (currently circa 1 ohm/ 16-20 W on rta's)? Any other keywords, hints and tips gratefully received. Cheers Apes.
