I am in the process of streamlining my sidemount setup and have friends who have switched the side which a hose connects to the 2nd stage. His reg was not a scubapro, but I am trying to do just that to a G250V. In other words, instead of the "dial a breath" being on the left side when the reg is in your mouth, and the hose coming out of the right, it would be the opposite.
