Just got a box of boge sr 3.0 ohm cartos I plan to use in a mini submarine tank. I felt like I was wasting Boba's bounty and Gorilla juice in my Novas so I picked up the Boges. I was wondering how many holes you punch in you cartos for 100% vg. My last carto tank flooded constantly wwith 70/30 pg/vg liquid. The flooding carto was a smokteck with 2 factory lasered holes. I just picked up one of those round aluminum carto punches and am wondering how many holes I should punch for this set up. 2 or 3? Don't really own a dremmel so slotting is not gonna happen any time soon.
