idk where this should go but i was wondering how big the difference would be for me to do this step up in stiffness. i am 6 feet and like 150 and im starting to hit bigg jumps. i hit anywhere from 25-50 so i was just wondering on what your recomendations would be. also, how much do you think would be a good price for spk pros if im throwing in kreations with the deal.
