Has anyone here tried Gibson flatwound strings?

I am considering getting these bass strings as the same gauges are my preferred set for roundwounds (40-60-75-95, there are some other sets that are 40-60-70-95, but I feel like the feel of the A string will feel off with them.) I looked around and don't really see any reviews anywhere about these strings, so I was just wondering if anyone has tried them and what they think. Cheers!
