Bronze or special steel oil pump drive

I have a solid roller in the 540 Hemi I'm building and I have heard so much conflicting opinions on using the bronze gear on the street . Apparently Crane have a steel gear for roller cams . Tho not to be used with HV high pressure pumps . I have a mellings HV . Yes they are high volume but pressure is controlled by bearing clearance once oil is warm , surly when cold and the pressure is controlled buy the relief spring the engine isn't being revved hard any way . Confused . Any help or anyone using either give me your thoughts .
Cheers
