Replying to New Season - New Ski- Help!

I live in British Columbia of Canada and frequently ski at the whistler ski resort. I am looking for one ski that can do anything from skiing on the groomers to skiing on powder, probably 40% powder and 60% groomers. I am 185 pounds and 6'2, I prefer skis that are not too surfy, which means a bit more control.
I searched the web for the best all mountain skis and this is what I have found :
Line Sick Day 105
Nordica Enforcer 100
Sky 7 HD
K2 Pinnacle 105

If anyone can give me suggestions it would be really appreciated!
Thanks
