Okay. Here's my quick reply. Your Aqualung Legend is a very nice reg - my wife bought one last year and I like it almost as much as the Sherwood Maximus I've been using for the last ten years. The Maximus is light, simple and extremely easy to maintain. I've hauled it through just about every diving condition imaginable, including muck, sand, ice and some other stuff I'd prefer to forget. It's been dropped on rocks, banged around on a hundred dive boats, neglected and abused in just about every way a hard working piece of equiepment can be. I simply flush it out with a hose and it has always functionsed flawlessly. I have never had jaw fatigue due to the second stage swivel and the under-armpit hose routing unique to this model. Sherwood chose to discontinue the Maximus a few years ago, and a Sherwood rep I questioned last year was unable to give me a logical reason. As long as I can still get parts, I'll continue to dive with the most reliable piece of gear I've ever owned.
