Comments??
Not much in the way of comments. You should be able to get the bottle on and off and it's best if you can do it with one hand.
Even though you're not planning on dropping it, like is sometimes done with a stage, you should also be able to drop it or pick it up and maintain buoyancy control...in case you do need to ditch it.
If the bottle is in the way when you move your head to look under you or if you have to move very close to the bottom you can cup it under your arm and roll your shoulders back. It's hard to explain but it pushes the bottle back and more along the side of your body.
