I think I own at least 1 or maybe 2
but all my skis have tips and tails that point up !!!
Why would you decamber the ski to find the crs? Here's a simple process similar with what I would use - see link below (this or just put them on the floor and mark the contact points) - so it depends how "firmly" you hold the skis, I guess - too firmly you'd decamber them:
Step 1: Find the running surface.
- Hold skis firmly together, base to base.
- Slide the card down between the tips until it stops. Keep the bottom edge of the card horizontal or you will get inconsistent results.
- Mark the sidewall of the ski there.
- Slide the card up between the tails until it stops.
- Mark the sidewall there.
- I recommend repeating this for both edges of the ski, and measuring several times until you get a consistent, repeatable result.

If you de-camber the ski when measuring the CRS, it don't think it says anything about how it skis at different angles and different types of snow... although it may give an indication of how it flexes... I don't think you'd get an accurate running surface indication: how much would you decamber? What are the support points for tips and tail that you'd be decambering against etc...
so, in my mind:
1. decamber to measure CRS gives no indication of how it skis in soft OR hard snow
2. measure cambered section (touch points) gives a rough indication of where/how it skis on hard snow
3. the rockers muddy the waters, the more the rocker, the more muddy
I guess it would be interesting to do some experiments on a few skis and see how different the CRS comes out when decambering vs not decambering...
