There are limitations to DADGAD, but I like working around the limitations. Backing people up at song circles is challenging, especially if they are playing something in Bb and I don't have time to use a capo. But then, using the middle three strings that are tuned like standard can let you play a few well chosen counter point single note parts. (This is a song circle where playing along is invited and I strive to never play louder than the person who is singing).

As a finger-picker, playing at instrumental, loud pub sessions can be a frustrating experience. Then, I try to come up with interesting bass runs and fills and figure that no one can hear what I'm doing anyway.
