Middle finger using right hand and ring finger using left. I have no idea why though.
I use my pinky to push my bottom button mechs.
I haven't used my Provari in months! My wife now has 2 Provaris and I have now 4 mechanical mods, everyone is happy happy.
I use my little finger. Though being left handed - I often find I'm unscrewing the battery compartment at the same time. This doesn't happen right handed though. I'm getting a 69 as I reckon the side button might be better for me...
First knuckle of ring finger with right hand, first pinkie knuckle on left.
My newest bottom button mod and atty my wife bought it in Manilla Sat. Am I a lucky guy or what!
