unshaped skis - dedicated right and left, or alternate them ? (edge wear)

gotta question about my new Rossi 9S (vintage a few years ago) which
I'll try out shortly.

the shop didn't mark one ski as the right vs. left one. I may be
rubeful here, but I'm used to having one ski marked as the right vs.
the left one.

If there's no real need to dedicate one to right vs. left because the
bindings are mounted just so, then

given that these are not shaped, what's better:
- dedicate one right and one left myself, so that edge wear will be
consistent (but lopsided per ski - the same edge will always be inside,
and presumably wear faster than the other, outside one)
- alternate per outing to get even edge wear

I tune (edges sharpened with hand tool (orange thingy with file blade
mounted at fixed angle) and wax), but I'm not into exciting stuff like
differential tuning (inside edge gets different treatment than
outside).

I am not K-Rad performance freak, but my main motivation is making my
equipment last and getting a good (ice/pack hold, slick) ride out of
it. Given that, is there a clear choice here, or am I counting angels
on pinheads ? (I'll insist that I'm not a pinhead though.)

TIA

I got them new at a firesale price ($100) a couple years ago out of the
local ski shop's warehouse cause they couldn't sell them after the
shaped ski revolution hit. They'll complement my 205 cm 7SK's that
I've been on since 1998. The boots are Rossi Equipe E's from 1996.
The bindings are new since I just set them up (I got Look P10s for
anyone who saw my previous post).

Why specifically would I want to dedicate right/left if my equipment
were really old ? Because old bindings would depend on precise
mounting position to give an optimal interface to the boot ?

FWIW my line of reasoning was that for decades, people learned to carve
on unshaped skis. I do various things that have a significant
technique component, so getting a pair of racing skis for $125 seemed
like a nice opportunity to continue that trend in the skiing venue, and
lo, the way they track, hold on ice, and move (lower pressure per unit
surface area due to length ?, like wide tank treads (or tires for that
matter)) have made them into great tools for sensitizing me to edging,
foot positioning, weighting, etc. I have learned to carve and
basically turn in whatever style I want to on them, so I'm satisfied.
(I'm sure that shaped skis would have given me a similar lower pressure
advantage cause they're fat, and I would have learned to carve the way
everyone else does today, "easy", the "shaped ski way", but WTF, I can
carve whether they're shaped or not.)
Whatever blows your dress up... thanks for your comments!

If you like the long stuff, you should look up Lloyd in Truckee. (LAL
Truckee). I started on 210's in high school and raced in college. At 50+
I'm now on 168's. My last pair of long skis are my old Salomon SuperForce
9.1S. I still have them and they're in great shape. I haven't skied them
in maybe 8 years.

With all the snow lately I've considered breaking out my 207 Elan r-3's. But
I didn't.
