Don't get me wrong, I thought the Visions were decent out of the box. But they just didn't perform anywhere near I thought they were capable of or where I wanted them to be. I tried a mod a couple of weeks ago just to open it up a bit more but it wasn't enough for me. So finally I took the knife to my Visions to do what I really wanted to do all along: No cup seal. Just the mouthpiece. Know what? It's awesome now. 
Here are the gory details on what I did. Works on Vision Deux and should work fine on the Vision Extreme as well. (I don't have any to test that on yet though but they look pretty much the same except for the new plastic which is easier to cut through.)
