That's an even greater argument FOR the manufacturer keeping things hushed. If that said racer gets dropped for whatever reason (poor results, poor image, etc), why would the previous manufacturer want to help that athlete get better results on a different product?
This years Alpine racing catalog has 5 different GS models to choose from for Men's FIS. Within that, there are different lengths to choose from giving a total of 8. Within that, there are many different flexes to choose from giving a total of way too many.
The athlete, along with his (or her) coach must choose the equipment based on how and where they race. The athlete has the choice of 21.5m, 24.1m, 26.1m, and 27.2m turn radius. Choosing which radius is determined by where most races are, and how powerful the skier is. A racer out west might benefit more from a tighter TR because snow is generally softer and having a straighter ski might require to much edge pressure to get the ski to come around (my experiences from Masters Racing here) and the ski plows before it hooks up. Conversly, a racer from Quebec would benefit from the more open TR because they are racing on boiler plate and can be really aggressive without worry of plowing. Having the 21m ski might become too unpredictable. The flex choices are based on how powerful the skier is, and how he uses that power. I prefer a medium shovel with a stiff tail because I am not small, but do ski a lot from behind. So, again, there are many choices to find the perfect ski without knowing how it was made. If it has bubblegum or ********e inside, what will it mattter if the ski works well for that athlete.
So now on to your ski. My 193cm WC model GS from last year has the same top profile as what you have. The profile is just that, a profile. Inside, there are still Powerchanels like on the rounded lobe models. Why is it flat? Because it makes it easier to repair the base burn along the edge line. and the te presses are not required to conform to the deep Beta lobes. This feature is most prevalent at the World Cup, where the water injected snow is so firm and the ski's edges so sharp, that the base is riding in the ice. This aggressive ice cuts into the base which no wax can protect. Coupled with a 100kg racer, the base gets beaten in one run. At the World Cup, a technician will use a router like tool and remove a strip of base from tip to tail and glue in a new strip and clamp it down. Hand work finished smooth and the ski is ready the next day with a perfectly smooth base, ready for the process to start all over again. Clamping onto a flat top makes it easier to get equal pressure without the use of complicated jigs. This process was originally only required for SG and DH, but GS races and racers require it there too. At this time, SL skis are less prone to this issue, maybe becasue the speeds are lower or the time spend on the edges is more breif.
