I can only speak for my own boy. He has plenty of drive - more than enough for obedience and agility. We also trained for working trials - and he is proving himself to be a capable tracking dog.
When I spoke to Karen and Doug of Kazeti I stressed that I wanted a dog that I would be able to do WT type training with, as well as agility, and wanted a dog with a bit of "oomph"

They were happy to recommend the Axel/Anja mating and they also chose the bolshiest, most outgoing male pup for me. I am extremely happy with Yogi. He is great with my children, is a steady and stable dog who I can take just about anywhere - his only small downside is that he has a rather sensitive nature. He is a thinker and certain things seem to worry him. However, he is oblivious to fireworks, gunshot etc, but he just seems to have a bit of a sensitive character at times. That isn't any great problem though.
Unfortunately his dam, Anja, died of a torsion at just six years old
It is definitely worth ringing or emailing Karen though and having a chat about their breeding plans and telling her exactly what sort of dog you are after and she can advise whether they may be breeding something suitable in the future.
