I tried a set of Chromes (.045-.105) and the tension was so tight I thought the neck was going to come off the bass. They weren't on for long. Tried a set of Roto Sound flats and they were a bit to zingy. Didn't like the feel of them either. Those didn't last long either. Thought I'd try something that was somewhat in the middle, like GHS Pressurwounds and I found those to be too stiff as well. They were on for about a week. As far as tension in a flatwound I'd like something that's the same as the roundwound strings I'm now using, which are GHS Progressives and the gage is .045-.105. Not loose by any means but not too stiff either. For me they are very comfortable. As far as tonally in a flatwound, not too bright but not too dead right off the bat either. Just want to try something in a flatwound but I'm not sure what would work best for me. Thanks in advance.
