Is the benefit of sidemount solely for cavers? Or is there a streamlining benefit that helps move the rig through the water?
The sidemounted tanks are clearly more streamlined as the valves are located under your armpits and the tanks really along your body.
They are also easier to move underwater: just unclip the bottom clip and the tanks are just attached with a bungee cord on the valve, so easier to go through a restriction.
