Look at it the other way around, why are you carrying the bottle? If it is because you want to do Tech1 and want the practice carrying it, then do that, Carry it, but don't switch. How are you going to switch to it? Who taught you the procedure for switching? How are you sure you are doing it Right?
A fair point - I guess it comes down to the temptation to go that little bit further but, as you rightly point out, without appropriate training. I guess it's not unlike wanting to see what's round the next bend in a cave!
Thanks though John - curiosity satisfied and eagerness reigned in
