I am running my first coil on my RM2 and was getting good flavor but not over the top. I moved the air hole a bit to line up with the coils ( as suggested by SuperX). I squonked longer thanks to FB. Wow, I hit the sweet spot! I cannot believe what a difference such minor adjustments can make to the flavor and intensity of the vape. I have not drilled the whole out yet and am loving it. I am getting the hang of the REO and it is a fast learning curve. What a great vape and now I understand why most buy more than one. Thanks for the help Reoville!
