I've got a Gamut (Lyon med. varnished) G string that I just love. I haven't found a decent D. I've used Pistoy light+, Evah Slap, Aquila, a couple of old strings from I don't remember where .They all sound congested and dull. FWIW the bottom 3 are Tempera Hybrids (older version) and I'm happy with them generally, but they seem pale and unexpressive compared to that Gamut G. I'm a pizz only player in public, though I spend a chunk of practice time daily with the bow.
