Ok,

I have decided to go with:

YP
SMB
PS
Walleye

I was advised I can just spread pea gravel on the western ends of both ponds about 3-4 ft deep for the SMB spawning.

I will probably have to put down a bed of #2 crusher run first, then pea gravel. As the bottom of my ponds is silty clay & sand. The pea gravel would just disappear if I spread it on that...
