It's a matter of convenience, I have a reel of bog standard gear outer and one of Goodridge brake outer in the garage(9 bikes to maintain). If the Goodridge is ok for the Rohloff then I don't need anything else, if it isn't then I need to choose another style of brake outer just for the Rohloff cable changes.
Any experiences of using extra stiff brake outers?
I have the cables my bike came with, so no experience of changing them but I'll make two points:
1.A Rohloff gearchange is accomplished by pulling two cables. There is no pushing, so the stiffness of the outer is nearly irrelevant.
2. I'll let Chalo Colina and Pete Cresswell make the other point. These exchanges appeared on rec. bicycles.tech some years ago:

Rohloff's external clickbox and shifter are wired with two totally
normal 1.2mm shift cables. You don't have to stock special spares for
that job. Depending on your setup, you might need tandem-length
cables. A quick survey with a tailor's tape measure will tell you if
you need to keep some extra-long cables handy; normal shift cables are
2.0m long.
Rewiring a Rohloff shifter is an _odious_ job, though. You have to
get a whole series of operations exactly right, in the right order,
before you fasten the cables down. The cables are fastened with grub
screws, and once tightened even lightly, they can't be reinserted into
the clickbox drum again. So if you forget any detail in the cable
component stack or in the routing of the cable, you have to begin
again with new cables, starting at the shifter spool. I think the
most times I have had to do this at one sitting is four times in a
row. (It's not just outright mistakes that can stop the show. If it
doesn't feel quite right and you want to try changing something, you
have to start over from step one.)
When the time comes to replace Rohloff shift cables, have every single
bit ready in advance. Have every tool available that you might want--
bench grinder, fourth hand, precision ruler, whatever. Have the
printed instruction sheet in hand and refer to it at every step. Do
not reuse a single piece of housing or ferrule, lest this seemingly
sensible and economical measure require you to repeat the job.
But hey-- at least it uses standard cables.

I'll concur with "odious".
For me the recurring problem was getting the length of cable that ?protrudes past the housing exactly right.
To that end, I cut a piece of housing to exactly the right ?length.
I've done several replacements with the housing piece as my ?length guide and haven't had any problems.
But I still have a half-dozen shift cables ready just in case ?when I start the job.

Hope that helps.
