Replying to Transition from soft to stiff skis

I'm 90% sure I want the 176 on3p kartel 98 mounted -2 as my next ski. I'm 5'9 140 and currently have the 169 2013 dynastar 6th sense slicer. I checked out the kartels in person and noticed my slicers were much softer and flatter (meaning my feet are closer to the ground).

I love my slicers but want something longer next year. Is adjusting to the kartel going to feel too weird? Should I get something more similar to something I'm already used to?
