My viola loves Pirastro Obligato
7 out of 8 found the following review helpful

Pros: They suit my viola - I find that they settle quickly after I've put them on and they stay in tune well. Good quality across the set so don't feel I have to get different makes for different strings.

Cons: I was confused about what tension to get. Tried strong but felt they gave my viola a slight 'metallic' sound at first. It settled into the tone I wanted after a few weeks but have gone back to medium tension as I feel they give me what I need straight away.

As good as gut for the amateur player.

Pros: Well balanced sound across all strings. Require only a short playing-in time. Stay in tune even through temperature/humidity changes.

Cons: Expensive

Other: First make of strings that I use as a complete set on my viola.

Lots of power and richness once settled in.

Pros: LOTS of projection, and a very good tone and pitch stability once they settle in. The difference changing to these from bog standard Dominant mediums made to my (mid-priced rather than excellent) viola is startling!

Cons: They did take about 10 days / 10 hours' playing to really settle, and during that time they continue to go flatter and the tone can be really quite rough (the C takes longest to bed in). For this reason, I'd only recommend putting them on with at least a week to go before a performance / recording.

I'm delighted I switched to Obligato

Pros: I acquired an inexpensive viola with steel core strings and replaced them with Obligato, as used on my violin (principal instrument). The transformation was amazing, as expected. Obligato strings play like gut, have a quick response, and have an even and beautiful tone. As an amateur violinist, I have not played a viola seriously, but can now anticipate rapid progress with the viola as a result of switching to Obligato strings.

Cons: They are rather expensive, but you get what you pay for.

Obligato proved most satisfactory!

Pros: An immediate response, a true and full sound which carried well in the church where I was playing the Telemann viola concerto (that's why I bought a new set)

Cons: A little slow (4-5 days) to settle
