Start simple with your first one. I'd say rub with S&P, no injection, and cook until probe tender. When you can slide a thermometer in like it's going into butter, it's done. It can be anywhere between 185 degrees to 215 degrees, so check for tenderness, not temperature.
When done, wrap in foil and and then a towel and put in a warm cooler to rest for 1-2 hours at least. Slice against the grain and enjoy.
