That butt looks great! Nice job! Lots of people, me included, like a dark, heavy bark on a butt...after you pull it, that bark adds a great flavor to the PP. How did it taste? It's really about preference...if you didn't care for such a heavy bark, you can lighten the amount of bark you get next time by foiling the butt once it reaches an internal temp of about 160*. It's good to splash a little liquid, like apple juice, on the butt when you foil it, then continue to cook until it reaches 200-205*.
Best advice is to try a few different methods and decide which you prefer.
