I agree with Bill and esshup. Plus adding G Shad into a pond with TFS does not always result in a viable population of GShad establishing. Many times it fails due to competition. What about tilapia ? Also if you are short on 3-4 inch BG then you have to many LMB in the 10 - 13 inch size not to many 16 + LMB. Adding 5 inch BG would also help plus feeding them if possible. GShad are my last option because of the risk of and cost to start over.
