Among the bulls you list I would be hard pressed not to use Unstoppable. However, Phil Lautner would tell you Paddy would be the go to bull on PB Angus cows. Who for the big framed females. None of my suggestions are new or hot, but they should at least make some really good clubby females. Otherwise, heatwave or clone if the cow can handle the bw and stoutness of that mating.
