Let me reiterate a point I raised earlier: They may not sell as well because they last so much longer. I don't suppose it's a 50/50 split between flatwound vs. roundwound adherents, but I wouldn't be surprised if a quarter of the bass playing population use flatwounds on a regular basis. If 25% of us were, the shops would still only see 10% or less of their sales in flats because they get changed so less often.
I change a set of rounds in a couple of months if that bass is seeing active duty. I keep flats on a given bass for years and years.
