GDK< I think you answered your own question actually, and here's what I mean. For a long time I always played a three finger G chord because it worked for me. I learned to play a 4 finger g chord so that switching to a C add 9 would be easier. You seem to be TOO concerned with the "correct" technique. If you can hit the notes the way you want to then that's your technique and it works, so keep on doing it. Lots of pickers play G chords different, barre chords different E chords different. Its all about what works for you. Hope this helps!! There ain't no better technique!! It's your technique.
