Both hands have complex tasks to perform. I'm not sure that either left-handed or right-handed people have any great advantage.
But do some left hand players use reversed bridge/strings and bow with left hand?
maybe? is this what you were asking?
@JohnG and others. I am left handed and play on a right handed string instrument. No issues at all.
A true left handed string instrument is constructed as a mirror image of normal. The bass bar is where the sound post “should be,” the placement of the pegs on the peg head is swapped (which is a good method of determining a left handed instrument in auction pictures), and so on.
Converting a guitar is easier for a left handed person, but again I see no reason to do so if a person has similar functional utility of both limbs.
