I currently have an MVP 2.0 and I have mini pt 2's and an aero tank. I also have a pt 3 with the air flow base. I seem to like the mini pt 2's the way they draw and hit more than the aero or pt3. I have seen the nautilus and kayfun mentioned a lot and was wondering is the nautilus as good as the reviews I am reading? Also, I have been rebuilding my pt coils and wicking with cotton and like that, has anyone rebuilt the nautilus heads? Or if it is better to go with a kayfun or kayfun lite plus? I do like the glass tanks so I wasn't sure on that
