I drilled mine out to 5/64 and I truly enjoy the airier
vape, but I waited about a month (holy smokes, I've had my grand for a month! Gnarly!).
It's great for my strong menthols (what
vape ~80% of the time), but I found I got a little flavor loss on lighter flavors, so made myself an ugly, but functional airflow control ring.
All in all I would suggest waiting a bit to see how you like the stock, then take stock to see if you really want to go bigger. You can never make the hole smaller. (That's what she said (sorry, I had too)).
