I have two of them and train with several. My oldest is HRCH and we are prepping for the Grand this spring. I think you will find the temperament of these dogs to be first class. Be sure to let them know what your goals are so they can match you with the right breeding, because some of their parings are super hot and not for the faint of heart. I know you don't normally hear that about British Labs, but these are field trial lineage dogs and generally are very high drive.
I live close to their HQ and one of their outpost locations so PM if you have specific questions.
