The key to good Q is "low and slow" this time and temp is pretty close to spot on. Use a good rub, plenty are available or you can make your own, the internet is full of recipes. I use a meat pump and squirt a few shots of salt brine in the meat too.
yessir it was good, i was amazed by how much i didnt lose due to shrinkage. i made my own rub, shipped the injecting, but did mop quite a bit. i would like to do it again for labor day, but the bossman is on vacation that week. i doubt they would let me bring my chargriller to work
