Gundog, I can see where it could be fun and enjoyable. If they had them anywhere in the South, I would probably take one of my Boykins and train them just for that. I know there are quite a few Boykins that are very competitive in the tournament circuit.
But you stated that it is a good way to put birds in front of your dog and keep them sharp in the off season. For me, this would not work. I train my dogs to sit to flush and shot. From what I have watched on TV and friends in the Boykin world that do the tournaments that I have talked to, sitting to flush and shot is too much lost time and you would not be very competitive at all. They tell me that the dog needs to be halfway to the bird by the time it is shot and that is exactly what I see on TV.
The way I hunt, if a dog chases after a bird on the flush, and that bird is missed, not only does he risk flushing up other birds while chasing that one lone bird, but he failed to mark the bird or birds that did get shot. But that is just how I hunt.
