what size hole to mod kanger OCC

[Dom]

I just got back from my local vape shop. They have the new kanger subtanks. They let me size the hole on the OCC with a drill bit. It was a hair smaller then 1/8 bit. I want to modify my occ but was thinking because of the small preexisting holes should i go a little smaller? If you have done this mod what size hole did you drill?

Let me start by saying at first I was trying to rebuild my stock OCC coil heads with NI200 and my results weren't to good
I couldn't get them to wick very well and was hitting TC all the time
So I drilled mine out to 5/32 and rebuilt them with NI200 7 spaced wraps on a 3mm screw it meters out at 1.3Ohms
They work way better than the original OCC they started out as
As of this post I have not tried the new vertical coil heads.
