I'm a little confused about some described methods of ascent.

Can I get a concensus from some BSAC instructors please.

1) Fin assist the ascent maintaining neutral bouyancy? Which sorta implies to me its a head up ascent method.
2) Use my BCD/suit to carry me up on the expanding air? Which could be in any orientation maybe (except feet first, with a drysuit).
3) Some other or mixed method maybe?

Many Thanks

1) Really is the same as 2). As soon as you fin upwards any
trapped air will expand and you will start to ascend. If you go
too fast then you dump some air. Too slow then you add some.

The only difference is that a few finstrokes gets the process
started sooner and removes the possible danger of putting too
much air in at the start, while your waiting for that initial
lift.

I concur with m' learned friend. The difference is safety.

If you are neutrally buoyant, a large breath in will start the ascent.
