Replying to Best allround ski for me?

I'm looking for a ski I can take anywhere. Will probably be used 60% in powder and 40% park/slopes.
Need something that floats well in powder, can be used in the park and are have grip on icy slopes. Waist should be below 100mm and length about 180cm. Should be pretty stiff and responsive too.

I'm using Salomon CR labs and Gun labs now, need something in between.

Was thinking about the Line Prophet 90, but are they really usable in groomed slopes?

Thanks for any answers.
