@bromeat what @gerygaub says is true, injection is absolutely faster though it requires an injector where rubbing it only requires the cure and a meat lug (or another container).
Bacon Taste Booster is something that is made to help fight off rancidity in the cooler and to help impart the old world taste with modern methods, like injecting. Now, it is most effective when you are tumbling as generally after tumbling you go right to the smoker instead of holding overnight but it can be used when injecting and holding overnight. So you might want to consider adding some if you inject, I add it when I inject and I do think that it adds something nice to the bacon!
