I was under the impression that half groove mains are recommended for high performance applications even with a non-cross drilled crank. The non grooved lower provides a wider hydro-dynamic wedge for better crank protection and the rods still receive plenty of oil. Maybe someone with more knowledge in this area can shed some light on this.
