I bought my banshee with a set of DGs on it. I personally like CPI and Paul Turner. I never have liked DG pipes.
I think my performance is okay, could be higher.
The one thing i do like about the DG is the sound, i dont know if all DGs are this way, but my banshee is really deep sounding and i do get compliments on the deep sound.
Other than tht, i dont recommend them and i have them on my banshee now.
