I'm playing Innovation Super Silver strings. I love the tone for Bluegrass, but I'm having some issues with the diameter of the strings. I sometimes play a little jazz & the diameter of the Ino SS strings hampers the use of vibrato technique and slides. Since I play Bluegrass more often, I have the tone I need most, but I would love to find a thinner / smaller diameter string with a tone similar to the Inov SS strings. Any suggestions? Perhaps I'm pushing against physics here? I have tried Thomastik Spiros. A good string, but they are not the answer to what I'm seeking.
