From what we are hearing & seeing, you just might be able to stock SMB. AaronM did great with them in a small pond in Phoenix AZ. He did also have a killer water filtration system as his pond was like 1/10 acre.
As Cody states in his recent article on smallies, the LMB eventually take over when they are present with smallies.
I have that same situation going on in my pond now and am getting ready to do a restocking of smallies while implementing a strict LMB slot limit removal plan.
I'm OK w/ restocking smallies every few years.
Like george says, the HSB are a no-brainer addition in my opinion.
I would love to have smallies in our ponds but HSB are harder fighters but they don't jump...
I'm very familiar with the geology and soil types in DavidV's area, from pictures IIRC are Post Oaks being in the Post Oak Savanna geographic area (David correct me if I am wrong) and in transitionnal Tertiay sand and clay area.
Great for water quality but a LONG way to haul rocks for smallies.
