You mean me
@bluemed?
Yes I said that, but does backmount diving require somersaults?
Anyway: I meant to say that, if you take the right tools, diving is very easy.
Sidemount would be one of those tools.
In backmount diving most people are locked into the horizontal position.
Everything else requires effort.
It is ideal (for example) to drop down a line, move around at a tightly restricted distance from that line and go up again.
But you can do that sidemount too.
Most other situations work better for a diver who can take any position, moves fast even against current and always can be counted on to be able to look after him- or herself.
Carrying large amounts of redundant gas as a beginners config, not as the advanced divers config, helps too.
And if you can do a somersault without stirring up the ground or simply stand on your head for more than a few seconds (no hands) or know someone who can do that using backmount, you must know as well that only a fraction of the people diving will ever learn to match that.
In sidemount things like that are 'beginners skills' often already tried and at least survived somehow on the first sidemount dive.
Sidemount being more secure and maneuverable in general are simple facts of diving.
Denying that (even to yourself) is nothing more than an uneccessary emotional reaction.
There is no need for that.
Backmount diving is not deminished in any way by sidemount being superior in most ways, not even if everyone would share that opinion.
In fact people should be proud of what they can achieve backmount, but it is time now or soon to move on to 'the new thing' and achieve even more with less effort.
Skills translate well and fast, everyone seems to agree on that, even if we don't agree on anything else.
