Wilson versus Clover fermions: A case for improvement
  We present evidence for improvement with tadpole improved clover fermions based on an analysis of the chiral behavior of $B_K$ and the quark condensate. Also presented are a comparison of the mass splittings in the baryon octet and decuplet, a calculation of $c_A$ using standard 2-point correlation functions, and the problem of zero modes of the Dirac operator.
