Kurt on RTF is from the Springfield area. A pro named Bob Willot is near Stockton Lake. He does mostly Hunt tests. Phil Brown is just North of Springfield and does mostly Hunt tests. There is a club called the SW Mo. retriever club. I think they still have a link on this site.
FFF I would use Bob Willet. I have trained with him and he has done a coupl of seminars for our club. Bob knows his stuff and will shoot you straight. If your dog has what it takes he will let you know and if not he will tell as well. Good luck on your decision.
