Hole size depends on your style of vaping, whether you mouth to lung hit, lung hit, the build, etc. Many folks get by just fine with the stock size air intakes in the Reomizers and other atty's. I'm a very long lung hitter that hits until the lungs are full, so I like larger holes in mine... around 3/64"-5/64".
Even have a Cyclone that has been enlarged to 7/64", near big enough to park a Cadillac in.
I see. Makes sense. I am a mouth to lung hit then. But I don't want to suck too hard. Lol, this conversation is getting weird. Ha.
Guess I'd have to see.
I'm gonna call Reo-Rob tomorrow.
