Nice post! Did you use your low slow rub recipe? The couple times I've done fast and hot I've found that the shorter cook time doesn't allow the spices to meld with the beef and mellow the result being a bit overpowering. So adjusting the recipe for the shorter cook time is needed. We have settled into a comfort zone running 250 to 275 with ever increasing results. I still consider this "low and slow" - running at 300 is more like "medium and quicker" while 350 to 375 is "hot and fast."
