Hank49:I would venture to say that tropical areas develop more better divers per thousand if for no other reason than the average tropical diver dives more just due to better conditions.
On the flip side of that, 100 dives in ideal conditions doesn't teach you to hone your skills as much as 10 dives in challenging conditions. If a 200 dives/year diver from the tropics came up for a 110' October wreck dive in New England, I doubt very much that he'd be as comfortable in the water as someone who's logged a total of 50 dives like that locally.
I wouldn't expect the opposite to be nearly as true.
Also, for what it's worth, there are lots of folks who love diving in cold, lo-vis conditions. It's also fun... if you're prepared for it.
