Hi9 vs LP 9"

Stupid Question Country,
I'm well aware of the advantages and quality of TrueHi9 3rd members in a wheeling and rock crawlin mode, but what of runnin up and down the slab?
I've got a 9" rear for my build up XJ, but for now it has to be my DD and I'm runnin' 60 miles a day min. highway. Since the Hi9 is "high" will highway speeds produce a gear oiling problem and wear out the rear prematurely? Slow crawlin and trail runnin seems a might different than runnin down the highway at 70mph?
Edumacate me.:explosion :wstupid:

As far as the oiling goes we have lots of them in daily drivers with zero problems. Thanks CRASH for asking though.
