Very good subject. I understand that sfboarbuster can do the hat trick. I know there are people with way more experience than me. But I hunted with many people before picking my catch dogs. I am not saying anything is the best because I think there are trade offs. But I got tired of calling dogs off because they crossed the property line. I saw the bigger catch dogs being used as RCD and did not have that problem. My Cd's are still puppies and are far from throw away dogs. I hope to use them as RCD's one should be about 100 lbs and the other 60-70 lbs. If I have a dog that bays anything but pigs it won't be hunting with me. I also expect my catch dogs not to catch anything but pigs. Maybe a skunk or two

but that ain't really trashing

But if my dogs can't grab that hog, shut it down and hold it until I get there they will be lead in catch dogs. I also think that if your catch dog is caught you better be busting through everything to get there. I know people think I am crazy for getting my unicorns. I sure hope they catch half as good as some people say.
But I have caught some pigs with just one bay dog. Just let the dog distract the hog and I grabbed them. But it only took once that it almost went bad for me to really want a good catch dog. For me I want a hog anchor. But I know Chance has used a Jack Russel for a catch dog. So I don't have the perfect answer just what I want.
