I've seen some pure danes and some good ones. I wouldn't say that they were common though. They can be a bit soft and the ones I have seen do not handle a lot of work that well. Some hunt very well though and have good noses.
IMO they seem to get sore feet easily. Again in my opinion though you don't need them 1/2 pit. 1/4 is enough. I think the guy that is breeding dane pointer bulldog crosses is onto something and may secretly even be an Aussie!!!LOL

I really admire the bull arab dogs but prefer the dane over the greyhound.
