Shoulder is shoulder, whether it is big or little. Cook it relatively slow and it makes pulled pork.
Personally, I am not a fan of boned shoulders. I think the bone adds flavor to the meat, and beyond all the temperature probing you can do, when the bone slips out of the roast effortlessly, it's done. If you're waiting for connective tissue to break down (which you are) there's no better sign that the process is complete.
I'll also join the choir singing about leftovers. It is just the wife and me, too. But, I rarely opt for a shoulder less than 8 pounds. We have pulled pork for a couple meals. Then some gets chopped up and added to fried rice. Then some gets crisped up on a flat top and made into carnitas burritos. Then some gets chopped and mixed up with cubed potatoes and sweet peppers and topped with a fried egg for pulled pork hash. If we grow tired of it before it is gone, the rest goes in the freezer until we get the urge for any of the many ways we use it.
I'm staring out the window at my BGE with a 9 pounder in it that I put on about an hour ago. I truly doubt any of it will make it to the freezer
