The sound of the string is easier to shape. It has a slightly bright tone and is noticeably more colorful in in the lower half of the string than the steel strings I’ve tried. The tone quality is still good beyond that, but response can get tricky in the highest position. I’m not sure how well it projects (though it kept up with the Obligato D when I had it on), but it bows out to too much weight. The Oliv “A” is takes about 2 days to play in and stabilize. It started unwinding after about 2 weeks but can reportedly last about 2 months. I would recommend using the heavy-gauge string because the medium still bows out with too little weight, though you’ll probably have more issues in the higher thumb positions. The light gauge is too sensitive to the touch of the bow. I can't give it a 5 just because of lifespan vs cost, but the Oliv “A” String has a sound that can’t be matched by steel strings. Grab one 1-2 weeks before a performance, but, otherwise, save your money.
