Hopefully somebody can provide better guidance. I just don't remember anything significant about them here on the site.
What little I do know about them is that when fed properly, the Channel x Blue hybrids grow considerably faster than regular channel cats.
Depending on your goals, that could be good or bad. I love channel cats, but they require a lot of management in a bass/bluegill pond that is not drained and seined on a schedule. My feeling is that because of the potential hybrid growth rate, they will cause more problems than straight channel cats. -- unless you really keep after them. Catfish are voracious top line predators and serious fish food addicts.
Whatever you decide on, just don't overstock more than you figure you can remove the following season. IMO, it is best to stock small quantities of cats each season -- just make sure they don't stay in the pond beyond a few seasons.
