Goalkeeping isn't a prototypical national trait for us Finns. It's an acquired trait, it wasn't a long time ago that our best goalkeepers were Myllys, Tammi, Ketterer. None of whom got close in the NHL.
No, a national trait is sometimes you've always had. And there the hard working, fast, dependable 3rd liner is the prototypical Finnish player.
That's a national trait.
For a long time I actually thought goaltending was one of the real weaknesses of Finland.
A national trait for Tre kronor/Sweden would be to play the game to the end without getting chippy or losing focus. Finland has experienced that at least twice (now Finns will in self loathing style claim that it is a negative trait of Finns which gave Sweden those wins :-) )
