Ski specific question?

Generally speaking wider skis are harder to put on edge and edge change will be slower so expect to work a little bit harder. Also, longer radius means you need higher edge angles for the same size turns as on a tighter radius ski. But the difference won't be massive. It's just about 1 cm wider and about 2 meters longer and in absolute terms both 84 mm width and 15.8 m turn radius are neither wide nor long and probably is an ideal sidecut for an all-mountain skis. How well/quick you will adjust to the change depends on your level of skiing. Skiing reds/blacks says nothing.
