We followed a version of this and used Jack Daniel's BBQ sauce because it is Vince's favorite, and we were too tired to come up with our own creative version.
The verdict: Really tender ribs, so the method worked, but the BBQ sauce didn't do jack for the ribs. We ended up with a one-note flavor that got to be too much by the end. Thank goodness for bogo. We will certainly try again (with our own sauce of course!)
P.S. Sorry about the bad blackberry picture. I'm still having computer issues.
