I have just started playing with this technique. I had a really nice smoked chop out a restaurant, so I did some research and here is my protocol:
Purchase a bone-in pork loin, ask the butcher to remove the chine or bit of spine so that you can later slice the chops yourself (between each rib). This was what my butcher suggested when I told him what I wanted to do. He tied the chine back on in case I wanted to leave it on, but I pulled it off figuring there's no point in shielding meat from smoke.
I tossed the whole thing in brine. Probably somewhere between 8-24 hours.
I dried and rubbed the roast. And smoked it until it had an internal of 130*.
I let it rest some, sliced it between each rib. and finished them on the grill with a glaze.
What I liked about the technique, is that between brining and slow smoking, you have a ton of control over your doneness, and can finish them on the grill without fear of over/under cooking. We all were really impressed with how moist they came out.
here's a pic of the finished product. these chops were jerk rubbed and finished with a jerk glaze (and served with some guava habanero rib...well if you are going to smoke one thing...might as well smoke two!) :
