Unknownwaters,
I live near Macon and have fished all the waters you mentioned, with the exception of Houston Lake. Lake Tobesofkee is a tough place for me. Blackshear is one of those places that really looks fishy... with a bunch of grass and Cypress trees, but I have only really had one good outing on that lake. Lake Juliette is a nice lake, Wildwood looks good from afar(never fished it), and the further down stream you go on the Ocmulgee River the better it fishes. There are also a couple of Public Fishing Areas (PFA's) besides Flat Creek in the area. Hugh Gillis PFA in the Dublin area and Ocmulgee PFA near Hawkinsville, the later has been groomed as a trophy lake. You can also try Lake Joy in Warner Robins/Perry and the Flint River out west (Shoal Bass).
Good luck
