Based on my description below, are there any questions or recommendations to my proposed set-up?

I have a 2/3 acre pond. The shape is halfway between a square and rectangle. Depth is almost uniformily 9-10 feet with steep banks on all sides. One of the shorter sides of the rectangle is "only" 6 feet for 20 feet from the bank.

It is a 25-30 year old pond with clear water and some muck about 6-8" deep near the banks.

I don't have any issues with plant growth due to the depth of the pond and watermeal and algae have been easily controlled.

I'm leaning towards a single diffuser like the Airmax PS10. I'm not overly concerned that every corner at every level is fully areated.

My goal for the areation is to support a healthy BG, LMB, and a handful of HSB population. I do have a Texas Hunter feeder and have been using sparingly but will be more aggressive once I start areation.
