I really doubt you ride at a 9 and 10, actually, there is no way you do. I ride alot harder than you, and Im only at a 7. The only way your DIN is that high is if your forward pressure is way off, and your bindings are completely messed.
Not to be rude, but from your eastern edit, I wouldnt say your ride very hard. I think you would be more than fine with a pair pf p10's, or regular Px12's. There isnt much need for the Jibs, unless you really want the "shock absorber" that is simply a gimmick.
