I’m a lefty too, and at this point in my life, I’ve played enough righties strung backwards..I refuse to do it anymore.
As with guitars, you get one lefty “choice” for every 100 right handed offerings. Oscar Schmidt does a pretty good job. I’ve got a beautiful lefty from them.
I’ve also found a company in Canada that is very left conscious, Twisted Wood. They were very understanding of my needs.
