Many have tried, but the single belt simply doesn't get enough contact
with the water belt pulley to turn it reliably, or at the correct speed.

The two pulley system is pretty easy to deal with if you use an single
8mm stud to assist with the shim installation.  Additionally, failure of
the water pump belt is immediately indicated on your dash because the
alternator ceases to spin.  Contrast this with the one-belt problem,
where the water pump ceases to spin (enough, at least) but the
alternator still works fine, providing no indication that anything is
amiss until you overheat.
