Well, I beg to differ. I had a New Braunfels Silver Smoker that I did every Mod you can think of to it, and was real proud of my efforts. At the same time I built my first UDS after seeing Bigmistas balcony drumpron.
I did nothing but fight and babysit the offset each time I used it and was very disappointed with the results, but with my UDS it was joy and happiness my first cook on.
The meats cooked on the Drum are unlike any of my other cookers, the drum has a flavor all its own. I did BBBacon on my BGE and on the UDS and my family can tell the difference between the two and prefer the drum hacon best.
I tried not to lose hope on the New Braunfels, but I found it not suited to my needs and reluctantly sold it and it was for the best, it was my goal to use it competing, but that would have been a big mistake!
With the Drum you can do low n slow or get grill temps of 350* if you want. And if you use a small charcoal ring it makes it even more versatile and fuel efficient.
You don't HAVE to add smoke wood- tea or woody herbs are a different change of pace.
