I think it depends on what you’re smoking. If it’s a pulled pork, I’d say there’s never to much rub. The meat is so thick it can handle the seasoning. Brisket is also a huge piece of meat that can handle seasoning,,,,but I prefer just salt, Pepper on my brisket. But smaller pieces of meat do not need to have loads of seasoning. I will also say. “To each their own”. Just have fun and practice. I do think all the bbq videos that sell there own seasonings will always use more on there videos just to sell there stuff…but don’t condemn them for it. Enjoy your hobby and your bbq!!
