Can't help I'm afraid, but do agree.... I learned the 'normal' fingering as shown in no end of chord boxes, and trying to do the more obvious one using the little finger is a bugger to get used to. But it's far better I guess to keep the index finger unused, as practice for doing barre chords. I've been trying to get used to doing A, C, D and E that way. But what do the seasoned real players do? ;-)
