Completely wrong, but nice try.
The STL is the single lamest excuse for a ski that I've ever seen, twintipped or not.
It's softer than my dick at an old folks home, and cheaply constructed too. I flexed one in a shop and nearly broke it...without putting much weight into it at all. I'd go so far as to call the Invader stiffer than the STL with no qualms. "But what about the "butterzones"", all you dick sucking morons will ask me..to which I'll reply "more or less the same concept as a trouble maker, look at both skis' profiles".
Furthermore, the Invader has a fully centered side cut and binding mounting position, whereas the STL doesn't. This means that the Invader is designed to be ridden at true center. Slapping bindings onto an STL at true center will cause it to turn quicker than it should, and it'll be squirrely at high speeds. The Invader won't suffer from this problem thanks to its adjusted sidecut.
Basically, the STL is WAY over hyped as a ski, and brings absolutely nothing new to the game, other than ridiculous softness in flex. You can, and should, do better when ski shopping.
