Duritz!
How important is it to you?
By that I mean, is there a hint of success at the end of it or is it just curiosity?
I could do it and so could a number of us, but it involves work, and I do not beleive the sire-progeny connection is all that important in MOST cases, in some sure, but not many.
If you think you have a hunch and it's worth trying anyway let us know.
Cheers.
