The best cello set on the market at this point is Thomastik Rondo. I have it on both my cellos, an old French and a modern Italian. Those strings are perfectly balanced, have great projection and at the same time feel very comfortable under the hands. My problem with Larsen strings, having playing them over the years, is the lifespan. They loose the resonance and response after only one month of playing. I thought it was impossible to achieve a great sound without having to combine strings, because cellists, unlike violinists, have always combined different brands for the upper and lower strings (eg. Larsen A/D and Spirocores G/C). Well, this problem was finally addressed by Thomastik with the new Rondos. Try them!
