milleti - welcome
I did the foil routine before and really did not notice a difference. What I did notice is that it added time to the smoke, let heat out of the smoker, and reminded me of why I retired my stick burner (tending to the equipment). The ribs were good but for my old tastebuds, the extra steps just were not worth the effort.
The great thing about smoking (and you see this at competitions), every one has their favorite method. Whatever works for you and yours is what counts. And experimenting is tasty fun.
Happy smoking.
