TI flats to my ears are the most musical sounding flats out there.
Having said that, they are also so low in tension that my heavy handed technique cannot deal with them. It's like playing rubber bands. If you have a light touch they'll suit you well.
Great flatwound strings with LOW tension.
I wish they were stiffer.
