Replying to Anyone ski Prior or Fatypus?

Looking at getting a wider ski to join my jeffrey 96’s. Currently liking the idea of a short sidecut (turning is fun) combined w being stiff/heavy (for going fast). Gonna be at mammoth primarily, with some japan trips planned. Narrowed down the selection to:
Prior CBC
Fatypus D-Vice
QST Blank

Any of you have experience with the first 2? I demoed the blanks last year and enjoyed them but thinking it would be nice to get a bit more of a twin.
