Large catch dog 55+ lbs VS small catch dog 50 and below

I know it's not really answering the question but I think both have their place. My favorite dog ever was a 55# pit/cur cross that was everything you could ask for in a catch dog. Get into small spaces, easy to load, easy handle, caught hard etc etc. I am currently getting more and more into the finder holders. The speed and power of these dogs is unmatched. For the type of hunting I currently do they are better for me now. Large agricultural areas and smaller properties. They have all the stamina you could ask for, jump fences, catch hard and get through the woods like a deer. Contrary to popular belief on this site they can fly through the woods. These aren't big lumbering dogs. They are purpose bred for years for this job.
