Vision Titanium Orchestra strings are targeted to orchestra players as well as chamber music players. The strings have been developed to replace gut strings and can be mixed and matched with synthetic core strings and pure gut strings. Ball ends are made of Titanate and the surface is treated in a special way.
If your e string is at all weak buy this one
Pros: Good clear tone and responds readilly
Cons: Nothing at all
Other: I have a modern Italian violin and whilst the lower register is wonderful the e string has always let it down, that is until I tried a titanium e. My violin now responds evenly across all the strings and playing as one of two violins in a small group , clarity and tone is vital, I love it !
