No worries Coops, you can have your say but did you have to be so verbose
Thanks Noel, 'Food for my thought'. Yes, the brood bitch is definitely the most important element. My main reason for being so adamant about this is that the worst brood bitch is clearly a lot more inferior to the best brood bitch than is the worst sire compared to the best sire. Virtually every sire is a dog with plenty of positives in his blood lines and has been at the worst a very good racer (therefore a proven bloodline). The same can not be said of all brood bitches.
Coops, I use "lottery" word a lot with regard to dog racing and therefore can relate very much to what you are saying but particularly when it comes to brood bitches, it is not difficult for me to identify brood bitches that give me a significantly better chance of getting a quality greyhound. The problem is that the pups cost a lot more.
To be honest, apart from the brood bitch aspect referred to above and the dangers of inbreeding, I really don't know "what is right".
