I would agree with that thread. I've vaped a couple hundred ml of Boba's in genesis attys/hybrids and find the 500 is hands down the winner. I tried 200 and 400 as well but the 500 wicks so much better.
Unfortunately its really hard to compare with so many variables. Heck its hard to make 3 wicks that work the same even with the same sheet of mesh.
But for me with AVE juice its 500 rolled fat with not much material and honking big hole. After the first few hours of break in I never have to tilt past horizontal with either my AC9 or iHybrid mod.
So by this statement, are you making your wicks WITH or WITHOUT a big hole in the center of the wick?
