Pond Mgmt 101

I feel that the pond is still out of whack and your info strengthens my feeling.

The bass having the build it had leads me to think it probably belongs to the upper end of the size bass in the pond, I'll have a better idea when I hit it again tomorrow.

I would leave those larger bass and harvest those 8-12" bass. I would fish some small beetle spin or similar sized bait in solid black or white. There will be more of the smaller bass and they will readily hit anything that moves.

Exactly, the beetle spin will catch most anything in there, with weightless plastic worms being best for only bass due to the high grassy / slimy snags along the shoreline.
