How long to cook baby backs?

Bill, read about your method of cooking spareribs using the 311 process instead of the 321 method and can only say that the spareribs I BBQ in my Weber smoker this past weekend were the best I have ever made. Tender, juicy with a nice bite!! What method would you use for babybacks, 211 since they do not take as long as spareribs? Congratulations on your championship win!! I really enjoy getting your news letter and all of the other information on your site!! I will be ordering your book soon. I am on a fixed income and have to watch my money very closely so I save up for things that I want.

Thanks Bill
