I'm looking for a heavier, crisper string than the Bel Cantos. They were great out-of-the-box, but honestly they are too mellow for me. I need a string that is more robust, and has quicker response. I don't know much about Spirocores, but would like to buy some. I've heard the Starks are very high tension, but what exactly does that mean? Are they harder to press down than BCs? I'm really just interested in bow response :)

Any Spiro Orchestra users out there?
