Clubby bull question

Im looking for a clubby bull who consistently sires offspring with the soundest back legs(i.e. tracks wide,stands square on hooves and not on the outer edge, flex in hock and set in pastern). What bulls have you used where you have seen a consistent pattern of them siring these characteristics in their offspring. A bull that comes to mind for me is unstoppable but i haven't seen enough of them in large numbers to know for sure.

Thanks  in advance
Zak

Does Point Taken or Unstoppable throw more middle and depth?
