Eugene,
The fiberglass centerboards have some lead embedded in them so that they don't swing upwards with water pressure.
I'd bet my fiberglass board had (has) considerably better foil shape than the typical cast board. I did do a little additional fairing when I had it out but it really looked pretty good. There is a section of "parallel middle body" but the leading and trailing edges looked good.
The cast board would offer a lower cg, but that shouldn't normally affect it too much because under normal sailing the form stability will have the most influence. The ballast becomes more important with heel.
Tod
