I kinda like Perps, but I find the sound a little thin, for lack of a better word. It occurs to me that I might try Superflexibles. That's the strings my brand new Pollmann came with when I bought it 50 years ago. I took them off pretty soon and put on Spiros for next 35 years. Now I am looking for a different sound and easier playing as I age and recover from a bad bike accident. At this point all my work is pizz, but about 1/3 of my practice is Arco. Any thoughts?
