First of all, congratulations to you (and to the wife) on your accomplishments!
But second, I was researching your dog's pedigree and I saw an interesting factoid worthy of comment. Back a few generations is the dog 
Super Gnat's Gr Ch Ace (6xW).
What is so interesting about this dog is the fact he is off of a 
son of Honeybunch bred to a 
daughter of Gr Ch Zebo. Well, the great Honeybunch was once bred directly to the great Zebo, and it produced a litterful of crap. In fact, it is almost a proverb in the game to use the example of Zebo/Honeybunch as proof that "Best-to-Best" doesn't necessarily produce squat.
And yet I have always said that, if you get an initial disappointment by breeding two excellent animals together, if you 
stay with it, and if you 
re-shuffle the deck with additional breeding tweaks, you can still bring out the excellence once again.
So I just think it is an interesting factoid that Zebo/Honeybunch didn't produce squat ... and yet 
their son and 
their daughter bred together produced a Grand Champion 
Cheers,
Jack
