i use to never foil and had mostly good ribs and some that were just ok (at my own fault through experiments) the first time I foiled them and added a little honey and little little water and juice and man to me in my opinion that the way to go. like everyone says and knows best def. try both ways. Also great idea using a glaze which I also like clark said. I'm kinda impatient sometimes and got in the habit of using the gas grill for that. I like them on high for not long at all, maybe 40.. or so seconds... till bubblin and lookin hot then I yank em off, Yes have burned em before and got to crispy, easy on that. haha its all so fun.
