Long story short, drilled my air hole out to 5/64, love it for a lot of stuff, loss of flavor for others. So instead of buying another RM2, inspired by one done by Pdib, I made myself and airflow control ring. My first attempt was functional, but it was uneven not very pretty at all and can be seen here: http://www.e-cigarette-forum.com/fo...-pretty-but-i-made-air-flow-control-ring.html.
So in efforts to clean up the look, I tried, tried again! I found a little piece of copper piping that was slightly larger than the diameter of the RM2 (which I failed to take a picture of), cut a piece off the bottom, cut a section out and drilled a 1/16 hole. Then did much grinding and sanding to get it smooth and pretty.
Again I post this partially because I am not very handy, so if I can do this, so can you! You could drill a bunch different size holes like Pdibs, but I only need two, the 1/16 of the ring and the 5/64 on the RM2.
Here's how it came out:
