The original Genisis were top fed and they worked well because gravity helped wicking. I never liked the taste of my own setups so I hunted down the people who raved over the "clear taste" and "perfect setups" of their gennies. I asked on every local vape meet over here if I could have a toot on their best genisis setup.
Well, to me they were all worse than what I could get out of a simple 306 dripper or a simple wick and coil setup in a RDA - with one exception: Citrus and menthol flavors work well in gennies, because they mask (or fit) the metallic taste.
I really wanted to like the genisis principle because it sounded logical, and I continued to find new things to wick with - 500 mesh, 7x19 steel wire, even had specially made ceramic wicks - nothing works like a simple fiber wick, at least not for me. I have an Orion, NGP, AGA-T, RSST, Cobra, Genisis-LV, Talos, because I thought the device might play the biggest role - it doesn't.
The current common tank style of bottom fed genisis atties has several drawbacks and is actually a step backwards from the original design in my view:
- leaking through the wick or fill hole
- wick works both ways and the discoloring of the liquid in the tank shows degrading quality
- wicking must work against gravity
- thick wick is a heat sink
- I have to fiddle with the positioning of the air hole against the mod
What I use now is either an Orion for the menthol, REO VVGs with Chalice, an Odysseus on a GGTS with a Kick and an electronic switch or a Kayfun on a Semovar or, it must be said, a Kanger Pro Tank on an MVP. They all have their strong points, but the VVGs are the go to mods for my VG heavy, gloopy liquids.
They are dripping without actually having to drip and I like that.
Everyone has their own values and I can understand how trying to find the best genisis setup can be a nice hobby, but while I fiddle with the hotspots, the ribbon Kanthal and the ceramic, I always have a REO within reach to have something reliable and tasteful to vape on =)
