^WRONG!!!!!!!!
Those measurements are the tip and tail heights not the rocker measurements. In the tech section it shows you the 3 different rossi freeski tip styles, and it doesn't say anything about one of rossi's two rocker types.
Check out S4's for example, those measurements are there, but they are deffinately not the rocker measurements (I own them, they aren't rockered).

Same with S1's, those measurements are there but s1's have full camber:

So yah, s5's have full camber. Also flashkick, your friend could have caused his own skis to rocker. My friends t-halls have a nose rocker profile similar to hellbents from doing so many nose butters.
