We have a couple race stock & regular dynastar sticks at home here
. the race stock SL (64 & 63s) are a matte finnish. the 64 is also quite darker in shade coloring, there is also a flat (not pre-drilled) plate on both. The stock versions also have a hand stamped serial # behind the heel mount followed by a size, the 64 will also have a black base in the stock version & Vert sidewalls. They are also lighter than the store version. Looking at them from the side, they are thickest under the toe & have a pronounce ramp toward the tip.
As these are my bears skis, I have had no time on them. Her take is that the real deal stock ski is v. fast & much quicker/lighter in sl, yet lackes the beef to make GS sized/speed turns
