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

My preference is the 50 and below catch dogs, honestly the main reason is more on the sentimental side because of my love and history with APBT, and next is because most of the terrain I hunt dictates what the most successful, most of what I hunt is really thick and a dog has to be athletic enough to maneuver through the saw briars and such and make it to the bay without being so wore out from having to Waller its way through the thick, and doesn't sound like a bull in a china shop either, I've owned and hunted several bigger dogs over the years and have had a few that were as nimble and quick getting through the thick as a smaller dog, but I don't run across those very often, aside from the hunting I look at the economic side of things as well and a smaller dog doesn't eat as much feed as bigger dogs and most of the time doesn't require the maintenance and upkeep that comes with the territory of owning bigger dogs, there's no right or wrong style, as long as it gets the job done and satisfies you that all that matters...
