I have about $500 to invest in a new piece and I have narrowed my way down to a Mobius Matrix, now which one I can't decide. I really like the look of the Ion/Clear bubblers; but from what I've heard the Stereo Matrix is better. Looking for some insight to what I should get. Also should I get the Ion or Clear. or the 60/65 for the stereo. I will be smoking flower ONLY.
