Yeah I love mesh too. 400 mesh is all Ive used, and it took me probably 5 or 6 wicks to get the hang of the whole setup.. But now.. forget it, it works better than I thought it would.
The whole needing to tilt the device upwards to get the
juice to wick, for me, is completely uneccesary, even on the thickest of juices. When chain
vaping a 100% VG, most I need to do is vape it horizontally once or twice. At least on my setup. Every atty is different, plus everybody rolls their own type mesh. For me, on my device, with how I roll, theres almost no aggresive tiliting required.
Ive tried silica in the genesis too, and its not bad either. But Silica and Mesh provide different vapes, and I like both for different juices, so I generally have both types of wick setup on different things. As far as wicking goes, I actually prefer mesh, I have to tilt and help it along with silica. So for Gennies I use Mesh, and Drippers, Silica.
