When I started diving (10 years ago) I purchased solid (ie. no flexible rubber sections in it) fins. I was in the dive shop a few days ago and was looking at all of the modern fins with flexible rubber sections in the middle and all sorts of advertised advanced channels.
Is it worth upgrading? Do people see decreased air consumption by switching to more modern fins?
