Congrats on the new ponds! Trust your instincts on the Black Crappie!!!
If your water supports trout year round, I'd go with about 500 7-9" yellow perch. The YP and rainbow both like feed, taste great, and will produce good forage. You could also add some golden shiners (10-25#), 20-40 smallmouth Bass, and 10-30 Hybrid Striped bass for additional catch options.
Being a mainly C&R pond, the trout can do quite well, HSB will not reproduce, SMB recruitment will be low, and YP will do well also.
