I think a lot of stuff we do is just based on personal experience and knowledge. Some people are giant Noalox fans, some like other products like vaseline.
I go against the grain on a lot of stuff based on my own personal research and level of comfort. We all kind of have to do that since this is an industry in it's infancy that's somewhat unregulated. I don't like putting vaseline on threads and I don't like putting it on o-rings that sit in juice I'm vaping even though it's recommended. I don't use silica wick either. A lot of manufacturer's use it, say it's fine, say it's approved. My research tells me something different, as what it's approved for isn't the exactly the purpose it's being used for in vaping. At the end of the day the lungs cannot expel small particles of silica. It's simply impossible. I've looked at a used wick out of my own devices and made a decision to use something different.
There are two extremely popular Genesis devices that have a bunch of brass in the atomizer chamber. To me that seems counter intuitive, we are all about the stainless steels and food grade stuff but we are ok with brass? Brass is reactive, brass contains lead. I'm not a tin foil hat wearing kind of guy but common sense would dictate that posts/nuts turning green(reacting) in a genesis vapor chamber isn't a great thing. Again, I decided I wasn't going to use them. Personal choice based on what I believe is happening. Maybe it's fine, maybe there is no lead being released. I prefer to get my lead from Salmon
When I looked at the iHybrid I was personally extremely comfortable with the design and features. Loved the top chamber. Loved the fused quartz. Love the fact that in some sort of catastrophic battery even it has that ability to vent through the switch. Thought it was a good design and I simply haven't put it down yet
