Wyo, the reason for using the middle ring and pinky for the "G' chord is that it makes playing much smoother after a while. I've had to un-learn so many people who'd been doing the other way (and wanted to play better) that I always try and get folks to do it the right way first. Your pinky will get stronger and stronger as you play. (and it's a neccessary finger when doing things like "Freight Train" etc.

Luv, Rick. I'm with you in spirit, but you'll have to bleed on your own.
