I have dominants too and I know what PV means about the C string being thick and unresponsive. Are they all like this or does anyone have recommendations for a slightly more responsive one?
No they are not all like this. I found the dominants to be a special case. Apart from being unresponsive, with the C string being the most sluggish, they used to leave unsightly black lines and blisters on my finger tips. I do usually play for a few hours a day though ( not all practice, I hasten to add).
I now have Evah Pirazzi C G D strings and a Larsen A on my viola, which make it sound lovely, are much more responsive, and are easier on the fingers. With these strings I just don't have to put so much effort into getting a good sound out of my viola. Having more responsive strings makes a big difference to how tired I get after, for example, a 3 hour afternoon rehearsal followed by an evening concert (particularly if the programme is quite physical, like Beethoven). The Evahs are high tension strings though, so may not suit some violas.
I used to use gut strings which I liked a lot, but they didn't last very long, and didn't stay in tune very well.
I have heard other viola players also like the Pirastro Oligato and Tonica strings as well, so they might be worth trying.
