Started with Blu and stuck with it a week.  Considering I don't like what they call menthol this was the hard part! Then on to Ego's ...
I was quite impressed with the look, feel and available flavors.
Next, after about 
three months a K101 and Protank. Glassomizers were the breakthru and point of no return for me.
Lately An MVP2, various ARO pyrex 
tanks and now fooling around with rebuildables.
