Agree with Jimster.
To the OP: Just want to add that they do ride differently. NS RC tech is rockered in the middle with camber near the binding area and the NS has a Vario Sidecut which has very good grip but can at times be hooky-ish at the tip and tail. Capita's Flatkick (3 stage rocker with elevated nose and tail) and radial sidecut (if not mistaken)means that the tip and tail are very catch free but may not grip as well. The SL-R rides very much like a cambered board, but with additional playfulness, and the tip and tail are very stiff. When you press the board, the board bends more in the centre than the tip and tail. This is quite different from many of the Capita models which tend to bend more at the tip & tail owing to the Flatkicks but less in the middle of the board (kinda like "hinge-points" on a deck, every deck has some area it flexes more at).
If ur looking for slopes/jumps and "a little flexible", the SL-R seems ideal - its really a middle of the road 5/10 flex and still more flexy than say a Bataleon Riot which is a popular jump board which u can charge with, but is no where as stiff as a freeride board. Hope this helps.
