Replying to Skis for brother?

Hey guys, I realize there's already 2,000 threads on this topic but I didn't want to shuffle through all the park/all mountain ski threads.

Anyway, he's 5'7", 130 lbs
-He skis in Washington
- Wants a ski that can handle soft snow/powder fine and still be able to carve well, and some side country
- Type 3 skier
- Basically unlimited budget
- He's not interested in park/riding switch in pow/jibbing trees
- Right now he's riding 165 cambered and is comfortable with the size

So far he's looking at the Blizzard cochise, Blizzard bonafide, Nordica steadfast, Nordica hell and back.
He was also wondering if a 177 blizzard cochise would be too big, I told him it wouldn't since it has an early rise. So my questions are, is it too big, is he looking at the wrong skis, and what other skis do you recommend?

Thanks in advance for the help NS.
