Smok RSST on Vamo V5 Question

[StateRoad84]

My RSST is sitting in the local PO right now ready to be delivered tomorrow. I have heard people say to drill the air hole out. For a regulated device like the Vamo, what size drill bit should I use to increase the size of the air hole?

I believe the one I used was 1/16. Works great. I'm even thinking about drilling another hole into the top and running dual coils.
