Brisket takes some practice... no matter what smoker you are using. Practice learning how your particular smoker works with the balance of smoke, heat, moisture, time. Whether to wrap partway or not. And practice in knowing what the brisket should look like, feel like, and what internal temperature you prefer, to make it perfectly done to your liking. If you had nailed it on your first brisket, you might still be chasing the perfect brisket, not knowing you had already achieved it. So having an imperfect first brisket is a blessing. Then again, is there ever a perfect brisket? Every one I make, I'm always chasing the best one ever.
