...you get the increased clarity on the low strings while not getting extra twang on the high strings.
That about sums it up for me too. When I end up getting a Dingwall it will be a four stringer and it will be for the greater tension on the E and lower tension on the G. I actually don't need the B string, got one of those on my guitar.Soundwise I believe the shorter scale on the G string especially will have a bit more fundamental. A lot of the time I feel like my G sounds a bit thin compared to the other strings on a "normal" bass.
