EMS plain gut is generally the best in the world . Sadly recently i have experienced a few inconsistencies - specifically with the .40 and .54 trebles - this makes it difficult when matching courses on my 18th century guitar. I'm experimenting with a 'single' arrangement but this is not ideal . EMS have been helpful .

Sounds good but previous one started to unravel while under high tension (56cm scale tenor high g). Applied some shellac on the new one and have not had any problems so far. Also currently using it for violin's e string.
