[BluesBelly]

I play alot in the key of G as it suits my voice well, and as a blues lover and player I prefer to barre the G which allows movement in my pinkie for picking up 7th's and such. As the progression moves to C then D I use the sliding C7 chord shape for both C and D. This works great for several keys as the movement is compact. As example: slide the whole works up two frets and your in A.

When I play open chords I play the low E and A strings with my ring and middle finger respectively which allows movement in the pinkie and index finger on the higher stringsto drop from G to G7 and other variations as well.

I suppose it would be important to note that my Acoustic and Electric Guitar playing technique is similar.
