When I was doing my first diving course I was told that my lift has to 
be enough for me and my buddy. Because in the case of an emergeny I may
have to save him, or he may have to save me. So how much lift is really
needed? Is there really a notable difference in drag between a 38lb and
a 45lb wing or a 55lb? 
I am talking about cold water diving, in thick (7-9mm and jacket) wetsuits
or drysuits. 

Bye, Jens.
