@ Tony, no, not mushy at all, still had some chew to it. It was a perfect as I can imagine it could be. We'll see what I think when I do a second one the same way.
If I was doing tenderloin or t-bone, etc. it would be about a 4 hour cook for me too but this cut has some internal connective tissue that can make the steak chewy and I wanted avoid that as it is hard on my jar. With the sous vide I did achieve this.
