One came off the grill having rubbed it up with Watkins Mesquite rub and a slight char for optics. To tell you the truth after having choice many more times than Prime I find no greater difference other than the prime was much moister. Taste was on par but not significantly so that it was measurably better than choice, it could have been just this particlar piece but I've had so many other choice pieces that were very good that I see no reason to abandon the standard. I didn't prepare it or cook it any differently, however I noticed as you might in a prime brisket is that the meat can be more forgiving because it holds moisture better. You can achieve the same results with choice, you just have a shorter window. So I find it juicier but not any tastier, and with this in mind at least for this grade of meat as a Tri tip I'll have no worries holding pat with choice.
