I tried Rotosounds once. I ended up switching to DR's Marcus Miller set. I've since gone back to trying GHS Bass Boomers, but I think I'm going to go back to stainless. The main reasons I liked the DRs better than Rotosound was the DRs have a different core so they have a looser feel when bending or playing in general despite the gauges being the same. Some prefer the stiffer feel that Rotos offer. I probably could set my action lower if I used them. Maybe I'll try them again here. For purely scientific purposes, of course
