This rib weighed in at 15.85 pounds. There are a couple of small areas where the bag is not completely tight to the meat but i got easily 80-85%. I am really looking forward to this!
If you want consistently better adhesion, slide it into a leg of pantyhose from the start. You can remove it after a week or leave it on the whole process. I gave not noticed any adverse effects either way.
Finished my 35 day dry age and the results were terrific! I will definately do this again. The increased tenderness and enhanced flavor profile are worth the wait. I ended up with 10 pounds of meat after trimming.
