Doug,
A single, high-quality Yagi will be fine. Even a six-element Yagi will
have a surprisingly broad pattern, and has sufficient bandwidth for
duplex service. Avoid stacking Yagis, and instead put your money into
one very good one. Stick to really heavy-duty antennas with solid
elements and welded joints, preferably factory-tuned to your transmit
frequency, so that there are no beta or gamma matching components to
loosen over time.
