Having slowly come to grips with E shape barre chords I'm now grappling with A shaped ones. The two popular fingerings I have seen involve one finger each on the 2, 3, 4 strings or alternatively using the ring finger across all three strings. I'm struggling with both but am having a slightly easier time with a hybrid fingering involving the pinkie on the 2 string and the ring finger across the 3, 4 strings.
However I haven't seen this taught anywhere. Before I put in too much practice I'm just wondering if technically there are any problems in using this fingering or if it will cause me any problems down the line.
