"Very confusing I must say, but hopefully I will figure it out sometime. I have done plain meats with not so good rubs you really could not taste in the bark at all, I have tried injections like Chris Lilly's, I have tried Texas BBQ Rub, vinegar sauces and sweet sauces. No single profile has gotten better results than another for me."
I will ad my 2 cents on this matter. And thats what it's worth.:-D If I were you, for the time being, I would pick a commercial rub. One that is well respected, pair it with a good commercial sauce and stick with it for a season. Work on your cooking skills. Be consistant. If you are swithching back and forth, this rub with that sauce, changing injections, theres no way you will be consistant. Once your scores start leeling out you can tweak from there. Good luck!
