Replying to Foil's VS SPK's???? Help please

Alright so I can get good deals on Salomon stuff, so I'm gonna buy either FOIL's 182cm or the SPK's 180 cm. I'm a bigger guy at almost six three who likes big jumps and pipe, and I only ride park when the rest of the MT sucks. I owned teneightys a year ago, but thought the foam core was a bit too soft for me. My thoughts are I want to learn switch sevens this year so I should get the SPk, but I figure the foils will be better off big kickers and on the rest of the mountain. Any suggestions?????
