I don't know if it is that much of an advantage, against Wisconsin anyway.
LaBahn is 200x90, so the Badgers are already used to a somewhat bigger ice sheet (and beat the Gophers there twice in Dec), and if Wisconsin thinks they need ice time on a sheet that is bigger still, the Kohl Center is 200x 97. And connected by tunnels, etc.
Ohhh did not know that!
Guess I haven't done my hw on Wisconsin, so what do I know
So I guess whichever western team wins will have an advantage over the east.
