An amazingly efficient filleter there. I also love the bellies and collars, hate to see them in the scrap bin too. I also rarely skin a fillet, kind of a heresy in my opinion.
Hate to say it but those looked pretty sad for flesh quality to me, nice looking but pale. Maybe that is the way they are in the Great Lakes. Also hate to see them unbled, that makes a lot of difference for long term quality.
