Sound like a fun pond, Blest!
I am not sure how prolific the PS will be. We have them down here in some of the reservoirs I fish, but they seem to be out-competed by the BG and GSF for the most part.
If the PS do get overpopulated, you might be able to put in a few female-only LMB if you had confidence in correctly sexing them. Or maybe a few walleye or HSB. If you were forced to correct with a few of a larger top predator, that might also cull some of your desired YP, but I wouldn't think it would have too much effect on your SMB population if they were well established?
