I have a breed with average size litters of around 6, my range has been from 4 - 9 born and from 3 - 9 reared.
If you were on my waiting list for a hoped for show prospect I would nto be having more than two people for each sex. the dogs will b e competing against each other. If you get two very close in quality but a bit different from each other then they will tend to swap places based on judges priorities or simply on variation on the day.
If your after a show potential pup you really do need to get higher up on the waiting list, no lower than second choice of the sex your after.
Saying that I have had litters where I would happily have shown more than two of a sex, and in others the wrong sex had the quality and the sex wanted for show has been just average.
If your intention is to breed a line of your own, and it is a breed where it is very hard to get a top quality pup for show, then getting third pick in an outstanding litter will give you a better foundation for you to breed something better, than pick pup in a litter of lesser quality.
But if your after a winner from the get go you will have to be more patient and convince a breeder you will do their choice pups justice. Often breeders are disappointed when entrusting a promising pup to a newcomer as they often end up not showing, or not lasting the course while learning (and obviously getting lower places until their skills improve).
