If your looking for light weight you will probably want a titanium regulator, I would recommend atomics latest T2. BUT... Sherwoods Maximus is a very good regulator, it is very comfortable. It has an underarm hose which I find is very enjoyable, and has a fine corse adjustment knob on the 2nd stage that you can adjust while you are diving. If your looking at saving a little Green though, and want a regulator that is just as good, but is a no name brand, I would recommend the Genesis GS2000 regulator. Its service is not to bad, and multipole components in it do keep the cost of replaceing parts down should they get damaged in comparison to the Maximus. Personaly this is my favorite regualtor over the Maximus and my opinion is a better regulator and a better buy to boot.
