I can't help you with the paper thing.
As to the effort to cook a chuckie---that is exactly why I cook 3 or 4 at a time. Leave them a little short of "done" somewhere in the 180s or so.
Then vacusuck them for the future.
When we want smoked pot roast or whatever, one just goes in a pan or roaster for an hour with some broth in the oven. Then we add the veggies and have a yummy meal in less than 2 hours total. No muss, no fuss.
Your chuck looks really good!!!
