If it really is light sanding, a non-woven pad can do it really fast by hand and give you a great finish. Not 2000 feet, but I did maybe 120 feet of reclaimed tongue and groove pine (made new tongues and grooves since the old ones were destroyed when taking it down) and all of my final sanding was with non-woven pads. I did have to take mill marks off first (I was using the former back of these panels since the original fronts were painted). Anyway, by the time I got to the "only needs light sanding stage" all I needed to do was hit them with the non-woven pads and it was pretty simple, flat on the flats and went with the shape on the v-grooves. I bet I did not spend more than a minute of light sanding per 8 foot board. I finished the boards with general finishes pre-stain conditioner, stain, and several coats of enduro-var via HVLP and simply repeated the light sanding with non-woven pads between coats. It would have been a nightmare to try and sand both the flats and profiles repeatedly with anything else.
By the way, I own an LS-130, and the only thing I've ever used it for was restoring the bases of some 100+ year old wooden columns; had to make three sets of custom profiles to match the entire base. That was in 2015 and I've only ever used it again to touch up said columns before the painters came. I do not think the LS-130 would be a good choice.
