Hi there all.

I'd like to get some opinions from people on the relative merits of
membrane drysuits Vs neopreane. I've always used neopreane and am about
to start a commercial diving course, so I'm looking for something rugged
and hard-wearing. I like the idea of the relative ease of donning
membrane suits and that they are comparively lighter, but get the
feeling that they don't live as long.

The school recommended Northern Diver or Otter. I've always used ND
myself but any thoughts on these or other brands is also welcome.
