I need opinions on injecting a Boston Butt. Not WHAT to use, but rather or not I should. My mind was made up that I was going to, and then I discovered this '4 hours to 135 IT' deal. Is it better to just not inject it? Is injecting it worth the risk? Is it really a big deal? I use an offset charcoal smoker so I don't have as much control as others on getting the temp up quickly without going too quickly. Also, could I just inject it after 4 or 5 hours when I insert my temp probe? That sounds like the best option but I'm not sure if that would be too late to help anything. Thanks.
