HUB's Manual vs Drive Flange

So over the weekend I picked up an e-locker off RME. Now the question I run into is do I install the brand new manual locking hubs I just bought or do I use the flanges that come stock on the Waggy D44?

The whole reason I wanted to run manual hubs was because I know how big of a pain it is to steer when your front end is locked. when you unlock one hub it relieves that stress. Now with the selectable locker I will be able to just unlock at the push of a button. I know that with the manuals I will get better fuel, but in all reality I don't know if the rig will see a whole lot of highway time. Yah it will see an occasional camping trip and I do want to drive it to some trail heads but that's about the extent.

Advise Please!!

Hubs, for sure. Like I said on RME, the limited slip will be doing it's thing any time the wheels are connected to the diff, even if you aren't in 4wd.
