My family and I like more "fall off the bone" than "Tug" ribs....
I have tried the no foil a couple times, but - i guess I am in the minority - because the 2-2-1 produces more of the type of ribs my family enjoys. It's a lot more work, but we like the results much better.
do what your family likes best. - we are just giving you our 2 cents... there is no right or wrong. LOL
Remember, experimenting is the fun.
