So.. I just did this:
http://forums.egullet.org/topic/1198...a-thick-steak/
With an assuredly lesser cut of steak than pictured there..
..and it came out a bit overcooked for my usual tastes, but it was the juiciest, most flavorful, tastiest steak I have ever had.
I highly recommend at least trying this.
My only caveat is easy on the salt if you're using salted butter. Mine came out perfectly, but i added "too little" salt in my mind so I could add a bit more after it rested to taste..
