I spend a couple of hours at a time hovering around a shark cage in 64-68
degree water, usually in a fair current.  I get cold even in 400g.  DUI's
claim of 40-50 degrees is far short of accurate, IMO.

200g is fine for a dive at Ginnie but useless for long dives. I am not sure
exactly what testing was done to arrive at these numbers but it probably
much more approximated average dive times. Scootering and length of
immersion led to an easy choice for us.
