Replying to SPK or Foil Boots?

My feet fit both the Salomon SPK and Foil boots, I plan on doing mostly park, about 90%. I also plan on doing some backcountry jumping in power as well. When I leave the park I like to do tougher stuff like black diamond runs, but not too often. I was wondering if you guys had any advice on what boots to get. Thanks.

If it helps I use K2 PEs (going to get more park-specific eventually, AR6s probably), Rossi Scratch 120 Bindings, and ski west coast.
