  Simulations that use the clover action in quenched QCD calculations have a
lower limit to the quark mass that can be reached, because of the fluctuations
caused by exceptional configurations. From this low statistics study, we find
that the twisted clover action, recently introduced by the ALPHA collaboration,
can be used to simulate quenched QCD at quark masses below those attainable by
simulations that use the clover action.
