After buying the Golden Mattens (NL 2310369-91, the best breeding male in the
  history of the racing sport) from Achiel Mattens we became good friends.  I visited
  Achiel at his home and had the chance to handle all his top birds and to hear what
  they bred and won over the years.  Super Boy's name kept coming up as the father
  or grandfather to his winning birds.  He said there was over 20 grandchildren of Super
  Boy that won in the top 1%, that Super Boy was the best breeder that he has ever
  owned.  Now you're thinking, "What about the Golden Mattens?" Wasn't he his best
  breeder?  No, because Achiel gave the Golden Mattens, when he was a youngster,
  to Ad Schaerlaeckens. 
   
  Super Boy is inbred to the Golden Mattens and has a fantastic race record himself.
  Not a big male, medium in size, strong perfect body, rich orange red eyes, foundation
  proven breeder.  Super bird.
