Pirastro Perpetual Cello 4/4 medium

As always, every instrument will respond and sound differently with different strings so what suits my cello might not suit yours. But, the qualities of these strings are very high and they will certainly do the job in a professional environment. I find the Medium better for use in an orchestra compared to the Soloist version for obvious reasons, but again, it depends much on the instrument and the personal preference of the musician.
