My 179 MRs with px12s are the perfect east coast one ski quiver for me. mounted 2cm forward of core center, they are super fun in the park, although I haven't gotten a chance to ski any deep snow or trees on them, I can tell they are going rip.
I've been thinking about this for days. I'd have to pick the ultimate compromise ski so would stop skiing park and only ski waist deep lines on donner partys
