Big dogs and thick brush myth

I haven't read any responses yet but have some further points to make regarding the big dogs don't do brush very well debate.
   Things evolve over time. There is discussion on this very forum regarding this issue and pig. used to they grouped and bayed I read, now they run. Look at the dogs most commonly used now in the US for pig dogging. cow dogs converted to pig dogs. Look at the pit bull. it's almost come full circle, from bear and bull baiting then to fighting other dogs now back to catch boar. Think of the transitions the pit has went through. Now look at the original boar dog. Why is it so hard to believe it would convert back to what it was originally bred for with a little coaxing. Why is it so hard to belive Americans can't do with a dog what other countries either have done or presently do. We are the world leader in developing things. We in our short history have brought the world from the horse and buggy to now being able to fly, speak to someone around the world in 30 seconds, capture moments in time and relive the past via video, we have walked on the moon, brought the life expectancy from 5p years up to 85 and so on and so on and so on and so on. Why can we not do with big dogs what other countries have done and are doing. Heck the work as already been done, the breeds already created, all it takes is unlocking the dogs ability. Hence crossing them.
   I've read on here pages upon pages of stuff about breeding better dogs. Breeding for this or that, now we have people on here breeding them to look alike. How does this just stop with bay dogs. It doesn't! My type dogs are just foreign to most here but the same concept that applies to breeding better bay dogs or strike dogs still applies to dogs you are unfamiliar with.
   I realize Finder holder types are a new concept here in America. That largely contributes to a lot of the false information spread on this forum and other places about them. There is lots to discuss about them, they are a new type dog to most. Most have probably never seen one hunt or hold but speak about them and tell me what they can't do when they have never even been with someone who hunts them. Same with large powerful athletic lead in catch dogs. I didn't own them, i owned pits for my lead in. The big cd's always performed as good or better in thick briars because of the exact opposite reason most on here sight. "They get hung up in brush" I witnessed time and time again the exact opposite. They were not my dogs, I'm not ashamed to say it. I had the little ones. Pits are my favorite breed but that don't mean I have scales over my eyes. We all have dogs that do well in the brush. it is not just unique to small cd's and bay dogs.
