Hey Ron, I smoked beef ribs and they turned out great but I call them dinosaur ribs. Refer to the 2nd link which Tony (DM) posted for my post.
Although they were good, they didn't have a lot of meat on them when cooked. In my opinion I would stick to pork baby back ribs, more meat and bang for your buck, but everyone has their own opinion. I wanted to try the beef ribs to get it out of my system and I am glad I did. I may even make another run at it if I find them on sale in the future.
