When I was at the bass symposium in Denton I got the chance to move the bow across Spirocore Orchestra strings on a bass for the first time. Of course, the pizz sound was AWESOME...but I didn't have any problem making what seemed like a decent sound with the bow (at least from my perspective). Moreover, there were fantastic players moving bows across Spirocore Orchestras like no tomorrow, along with Helicore pizz strings. What gives with the Spirocore Orchestra arco disrespect? It sounds like a great string to move the bow over...even a little girl was knocking them out and sounding great.
