These strings are a big change, but very good on my cello. The upper register is less edgy, and that has inspired me to feel less shy "up high". Since I've changed my strings, I've received many compliments, performing in churches, and also in very dry acoustics. The D string is more lively than my Larsen was, and the G and C work well, they seem comparable to my previous Spirocore Tungsten mediums. I do feel the need to compensate for a somewhat delayed response of the A, I need to really put a front on each note to get it to sound vibrant immediately, but that seems good, and I think it's the trade off for the warmth and roundness of the A in the upper register, which I'm really loving. Highly recommend!
