I don't like gimmick ways to add range and other things.
I personally play on an Edwards 1H... a tad bigger than a Bach striaght one. It's a pipe of a mp and if you get out of shape it takes a while to get back at it. But when you are in shape the amount of sound you can get is just insane. The power is great and I still have decent range as far as legit stuff goes. All of those quick fixes haven't ever done much for me.
