I don't think Kerry Blues are the gamest for a minute. Just that some strains are feisty and ready to go,have a good nose for following sent, and have a certain skill when engaged, depending what you do with them and the individual you have he can Hunt. I don't know what the working wheaten are like, many don't look to good as a worker.
I agree neil....you put quality apbt to a kerry he will be a better fighter, gamer also.
