Who makes a 5 String Flat Wound Set w/tapered windings ?

[buzzbass]

Just like it says, I need a taper wound 5 string flat set, so that my thumb 5 will intonate properly on the B string. I have a worn set on there now and can't remember what mfgr I got them from

La Bella DTF 128B = tapered.

Sadowsky Blue Label Flats... Both 125B and 130B are tapered.

If you can post a couple of pics of the strings, one at the headstock and one at the bridge (including the ball ends), we might be able to ID them for you.

Optima Flats are tapered, too.
