Hey Big_Pond, I would go for it. Maybe my experience had something to do with what I did. I can't think of what that might be, as I have not lost any other species of fish.
My points that i have made were from my perspective and not intended for you take as the gospel. As far as me stocking blues in the future, it will not happen. But this is because, to me there is little advantage to putting both species in such a small pond. I am getting tremendous growth rates from the Channels and also want good growth rates from the bass and the blue gill. Adding another predator to the mix was probably not the smartest move on my part.
As for you and what you want, only you know. I say go for and let all of us know what happens. Good Luck!! By the way I just got the picture developed and will be posting it the weekend so stand by.
