choke should have an impedance several times the elements center
impedance on the lowest frequency the yagi is used on."

Why not just directly ground the centers of the parasitic elements to the
boom?

I think Mauri's reference to a "choke balun" on the driven element was
for a few turns of coax wound up at the Yagi feedpoint, BTW.
