So I have a new Vamo V5 with an airflow controller on it to protect the 510 threads. When using a protank 2, I have to screw it all the way down or I get tank wobble. When I do this, it really makes the draw tighter than I am use to with my protank 2 minis and ego batteries. I have a precision drill kit and have thought about making the 2 holes in the stem slightly larger. Was wondering if anyone else has tried this. I have 5 extra bases coming in the mail, so if it didn't work, I can put an original base back on. Any thoughts? Thanks.
