The Ken Smith strings are made by GHS(?), so I believe they are similar to their pressure wounds. I preferred the Smith website over GHS for the ease of buying a separate C and B. The Smith makes their C at .28, which I like. Both use a proprietary alloy? The SIT Silencers use nickle and are easy to buy as I dont need to pick a seperate C and B. The Silencers are cheaper. The Silencers are hex core whole the Ken Smith's are round? On the 6er I play fingerstyle with and without nails on my index and middle for the most part. I run passive with Bart soapbars. I save most of my slapping for the active 4 string with rounds. I want semi-quiet / semi-smooth strings I can shift chords gracefully and gliss for legato passages. This is a technique concern but strings are important. I'd like some zing available to me, otherwise I'd use TI flats. Ideas on the overall subject? This is not limited to the two strings in the title.
