UD may have a better memory than me, but I believe Felix from the Young Rascals and Steve Winwood also pimarily used left-handed B-3 bass.
Trio work with a strong guitar or horn lead player is easier than playing a duo with a strong mix of instrumentals. Keeps you on your toes, is a work-out, particularly if you do a lot of up tempo jazz selections, but extremely satisfying.
Let's keep those left hands "walkin".
