  We present Monte Carlo data showing the comparison between the parton shower
generated by the standard DGLAP-CS kernels and that generated with the new
IR-improved DGLAP-CS kernels recently developed by one of us(BFLW). We do this
in the context of HERWIG6.5 by implementing the new kernels therein to generate
a new MC, HERWIRI1.0, for hadron-hadron interactions at high energies. We
discuss possible phenomenological implications for precision LHC theory. We
also present comparisons with FNAL data.
