Alum vs. babbit brgs?

Builders preference to Oiling and Load Carrying, always trade offs to the decision....just my thoughts as in "IMO", no wars wanted.
I see no problem with the 1/2 groove Mains below 6K Street Engines, and probably better in that application for long term load carrying, and still plenty of Oil for the Rods.
That said,
I prefer the full groove for the harsher environments as rpm, Compression, and demand for Oil by the Rods increases with Vertical Clrc., Side Clrc.in pairs, etc etc.
But as I have seen in the past....
EITHER will work just fine in both applications, so go figure ?
If you are concerned...call Hughes maybe ?
