I put thes two in at 131 for two hours based on Reddit recommendations, and discovered that the internal temp had only gotten to 124. Put them on a cast iron griddle on the grill (closed lid) rotated every minute, and brought the temp up to 130ish. The sear turned out great, and fortunately I had some guests who preferred the thin ends that got up to 138 and 140. Lesson learned. Also, Kinders The Blend, in the bag for a few hours before the bath, and again befor the sear is excellent. Note that the grey band is more than what I wanted but the added flavor of the crust is worth it. Hope my experience helps future cooks. Cheers!
