The only possible negative I see in HSB's is their lack of "sustainability". They don't reproduce and you aren't going to catch all of them. Thus, I would worry about restocking HSB bait for the larger ones. A grow out pond like George has might alleviate the situation.
Concerning catfish, I have them and am trying to catch them. They have gotten too large but that is a problem I have always aspired to have. When I get almost all of them, I will restock with 12 inch ones. I love them!
