Replying to Big Mountain

My dad is looking for a big mountain twin and asked me to help him choose :)

i compiled a list of skis i thought would work for him:

amplid teddy bare
line motherships or bacons
Ninthward THA
Armada JJs
Fatypus D-Sender
Surface Tj Scheider Ltd
Faction 3.Zero
Bluehouse District
Nordica Blower


Basically every brand has a ski in this category (fat but not too fat) around 100 - 115 waist width

right now my top five for him would be:
teddy bare
motherships; bacons
jjs
tj scheider ltd
blower

he wants the ski around a 181 length and will use it for everything on the mountain and not much park.
he is 5'10 and is around 170 lbs.

what would be the ideal ski for him? feel free to suggest skis that aren't on this list
also whats the difference between the motherships and the bacons? are the bacons just a tiny bit wider and softer?

thanks
