I've decided to buy the HG Skis Spitfire Stingers and I am wondering about the dimensions of the skis and size bindings I should get. On the website the dimensions for the spitfire stingers are the same as the subway stingers. (even the length, they are not 178s but it says they are)

I am wondering if the dimensions are correct other than the length or if they typed out the wrong dimensions.

I mainly want to know because I am wondering if I should get the rossignol FKS B95 pivots even though it says the skis are 96mm underfoot. Also I am not sure how wide skis will affect my skiing in the park. (I hit rails a lot more than jumps and I would say I am an intermediate to advanced park skiier)

Please let me know your advice for this situation, thanks.
