I play mainly in single "Drop D" with just the base E tuned down to D. I've chopped the end off a Shubb, so that it doesn't cover the top two strings. That gives me DADGAD equivalent in E on the open strings. The fingering for DADGAD on the top two strings is of course non-standard, you have to finger two frets down from where you would in real DADGAD tuning. But the real bonus is that as well as getting the DADGAD sound you can play your chords over it, just as you would in Drop D, so long as you cover the top two strings.

Because losing the end of the bar unbalances the pressure between the bar and the pad at the back of the neck I do have to position the capo carefully on the back of the neck and perhaps have it a bit tighter than normal to stop the bottom D buzzing, but by keeping it as close a possible to the fret I avoid intonation problems.
