I have the standard gauge labella flats on a jazz style bass right now. I like them but would like a bit more growl and complexity to the midrange. I've seed description of the sadowsky flats as sounding very close to the labellas. Others say they are brighter and noticeably different. Looking to get more direct comparisons - if you've tried both let me know what you think. Please don't suggest the TI's - the low tension of those is not for me.
