Another 2p's worth
Talking about air migration i've done the opposite to a lot of the other posters here. i.e. Most of my diving done with a neoprene drysuit now changed over to an Otter Membrane.
Have to say I havn't noted air migration any more of a problem in the membrane than the neoprene. I think however its good advice if you feel prone to this to use your BCD more for your bouyancy control. Theres been numerous why's and wherefores on which you should you ie suit or BCD I consider this is down to the individual. Never felt the need for ankle weights.
Changing the subject to the other point mentioned.
Whats the big deal about "Jet Fins" bought a pair years ago and consigned them to the shed. Are they "supposedly" better than conventional fins?
. Not much difference from my own experience.
