That's a pretty good video Enrico.
When I have done them, I did trim/scrape a little more fat off of them as there is a lot of marbled fat in the meat.
The first ones I did I used a my regular butt rub and thought they were too seasoned so from then on I just use Webers Steak and Chop with a little Lawry's season salt.
Then the easy part. Put them on the smoker ( I do 165 degrees) with some of your favorite wood, and let them go for about 4 hours before you check them. They are usually thick enough between the bones to put a temp probe in, or just cook them til you have good pull back. No need to foil unless you just really like to.
And that's it, pretty simple I think. Good luck
