The discriminating fancier will notice that greatest "RBJ/Bolio" dogs weren't just involving any old RBJ dog and any old Bolio dogs ... they actually involved specific breeding combos ... and they involved specific dogs.

They pretty much involved Yellow and Buck, or Yellow and a heavy Lady In Red dog (as Lady In Red was Buck's sister).

I don't think using other Bolio dogs, and any old RBJ dog, has proven to have the blockbuster results that Buck/Yellow and Hollingsworth/Yellow dogs have had ...

Just my observation,
