Also Rednose, If I could get my hands on a good Presa or Boerboel for protection, I would not say boo LOL!
Presa's and Boerboel's are no joke! but the one I really like because of how well they move for their size and they seem to be doing pretty good in the protection world are the Cane Corso's. I really like how well they move for their size, and from what I have seen they handle the training pretty well.
I got a friend that keeps corsos. His are out of a line that is too hot. The Main stud of that line was notorious for biting show judges.
His dogs are not as sharp, but they have that overly dominant temperament. Have to put a foot up their backside from 6 weeks until they get with the program. That I'm not into. I love that old school mastiff temperament: laid back unless called upon or needed. They can be hardheaded as pups, but with proper handling become great dogs
