I'm not a fan of the cross. It can work well or it can be a disaster(within a litter even) I'd rather see a nice blending of well thought out breedings done within lines(WG/Czech is my favorite 'mix') than the SL/WL matchups. More often than not it seems to be the flavor of the months in those, vs what actually might work to improve whatever they are trying to disguise or get rid of. Or it is a breeding of convenience, you like this dog and that bitch and breed them to see if you can get a deep red sable with great conformation.
I think it's Hillbilly BYB breeding what they can out of ignorance to have a litter to sell.
