It can just be wrapped around the wick without mesh if you like.
I`m just having a try with an Ekowool (basically braided silica wick) "U" wick in the AGA-T2, working well so far but I`ve only just rigged it half a tank ago so too early to compare with the many other set-ups I`ve tried.
One thing though, it does seem to keep the coils at the top of the wick better fed with juice and stop them drying out faster than the lower coils.
Simple to do
