Curiosity got the better of me and I bought a set of the extra lights. The G, D and A strings were fine, in fact rather nice, but the E string was like it was from a completely different set of strings, which made the set unplayable. I complained, genuinely believing that the E string had not been made right, it simply couldn't have been intentional. I was sent another set. Same problem. Maybe played in a certain way, and EQ'd in a particular way, they would be ok, but to me that is not how a set of strings should be - there should be cross string consistency full stop. I have put my TI Flats back on.
