Since I stopped playing electric guitar, I've nearly stopped playing any bar chords. I've long used my thumb wrapped around my acoustic neck for full chords. I have big hands and can double up on strings, I also like to change the voicing of chords, from time-to-time for effect. For example - you can get an tremendous range with the low E dropped to a D, and play a D chord with an added high A at the 5th fret of your 1 string using your little finger - then play a G chord by sliding up just a bit to fret both the 1 and 2 strings at the third fret for the G and D, and the 5th fret with your third finger on the low E, blunting the 5th string as you do - again, a very full range with simple fingering. Fun stuff!
