A selection of simple kinematic variables chosen to be sensitive to
different aspects of ttbar production in W + \geq 3 jets events are studied.
Monte Carlo comparisons are made between different top generators (Herwig,
Phyhia, and Isajet) and a QCD background generator (VECBOS).  Finally Monte
Carlo predictions with the ttbar fraction constrained by the SVX b-tagging
rate and measured top mass are compared with 110 pb^-1 of CDF data.  We
conclude that the CDF data is consistent with standard model predictions using
the studied generators.
