So I was reading about making the hole bigger on RM2. I didn't measure the hole size but made it bigger with a safety pin. WOW the metal is very soft 
Now 2 of my RM2s have big holes and i don't like it. Well one is ok with 2.0 ohms on my Grand but the other is too airy on my Mini 2.1 with a 2.50 ohm coil.
Any way to make a big hole small again
