dimpled radiator

According to the radiator shop I am using, the hot (no pun intended) 
core for maximum cooling these days is a 3 row dimpled core.  i guess 
the theory is similar to a triple pass inthat the dimples slow down 
the water for more cooling.  It was in a trade magazine (I guess 
there's a trade rag for everything) as recommended above 4 row high 
density.  I'll let you know how it works!
