Replying to Waist width whats up with that?

What up folks
Trying to decide between a Vision 108 and a Vision 118 for my touring/resort ski for British Columbia. Im from the far east coast (literally Newfoundland as east as it gets) and have never really experienced the amount of pow that’s coming my way once i get up there. I currently ride some ON3P Kartel 96’s and they’re perfect for where im at but id like to hear some opinions.
Kicking Horse is going to be my new home resort so ill need a freeride oriented pow ski. I just don't know how wide i should go. There isn't much online about the 118 and id like to hear some comparisons between the 108 and 118 if anyone has any or any other suggestions. Also looking into the sakana and JJ UL
Cheers
