I was a little bit scared not being able to use the bow on these strings but the sound is gross. I love these strings. I play 90 % pizz but uses the bow now and then and it works just fine. I have to put a little more pressure with the bow though.
I wanted a thick and groovy sound for bluegrass, jazz and gospel and I got what I looked for. These strings are thick, mind you. I had to drill a larger hole in the string holder. The sustain is a little shorter than with steel strings but that's the price you'll have to pay for this wonderful sound.
My next strings will definitely be the same.
Best of luck
Johnny
