Good point bill, there are lots of other important factors.  But this 
disussion is about thick vs thin.  Metal, coolant, air , and fin qualities 
have to be judged separately.  I am assuming these qualities are the same 
thick and thin.  

As far as delta T being smaller for thin rads, you miss one of the main points 
in the example above.  Slow down the air in the thin rad and it collects the 
same amount of heat that the thick rad delivers.  No matter how thin, slow 
down the air enough and the delta T is the same.  All factors can be set to 
the same - coolant heat loss, delta Tair, mass of intake air, weight of the 
radiator etc.  The only major differences are speed of the air and thus the 
drag of the air through the rad.
