Tungsten and silver on synthetic core.

Pros: Produces a full, rich, rounded sound. Responsive and yet with the desirable "thick" tone that one wants of a c-string.
Other: It is good to have the c-string with variable tensions for different length violas.

Pros: A soft-tension C-string for my 16.5 inch viola with a string vibrating length of 380mm. Very easy to play, nice tone, usual quality item from Pirastro. Once it has stretched itself it stays reasonably in tune.
Cons: Very slightly 'flabby' when faced with fast/low-pitched/loud passages. The medium tension version (optimised for 370mm) is not significantly 'quicker' (but these comments are very dependent on the viola's 'natural' characteristics).
Other: Similar positives for the Obligato/soft G-string and D-string.

Pros: This 'strong' tension string suits my instrument better than anything I've previously tried. That is not really a reflection on the string itself, but on the way it interacts with this particular viola. In general, I like the sound of Obligato strings on this viola -- but not on my violin, which is already "dark" enough in sound.
Cons: Nothing, yet.
Other: One can only laugh at being asked to review a viola string at all (given that everything depends on the instrument and context). This one was at least fitted, whereas most string purchases are bought to replace spares.
