Not sure about crosses, i have a pure who i must be honest was an intentional showdog, but i got bored with showing and gave up, i have had her out lamping a couple of times and she is showing good interest, i think with time and patience she will be good. She is very loyal and has just as good obedience as the lurchers. She stands 29 to the shoulder. Will never be breeding from her though as she is spayed, sometiimes i regret it though. She is incredibly fast and for a big dog can turn well.
