Tshad would be a good option in many larger southern ponds. However, not many people have SMB in ponds far enough south to also support Tshad...
Gshad, are a struggle to keep with LMB, let alone SMB. Unless you had a pond with 2/3 of the population over 15" and 1/4 over 20", Gshad would make a mess... Even then, it would be risk. SMB have substantially smaller mouths than LMB. I think there are better forage solutions for SMB than Gshad. SMB are far less piscavorous than LMB as well.
In a pond I was looking at raising trophy SMB, I'd use RES, crayfish, LCS, bluntnose minnows and spotfin shiners as the forage base. Once the SMB reached the 18" range, I'd consider stocking GSH as well. That is for a northern pond where Tshad were not an option.
