@ Basscataz: Thanks for the input, I'll check them out.
@ tekdiver: I know, I know - and actually I like Sunbeams so much because they sound so little like most other rounds I've tried, you know, with that soft blooming warmth they're noted for.. I'll check out the pressure wounds.
I asked because the bass I intend on installing them on has this beautiful brass custom bridge which gives it great sustain, but the brightness and bite is a bit much. I'm waiting for its Sunbeams to oxidize a bit, since I know they really warm up after a couple of weeks and level out with the edge. I figured a half-flat string profile would temper the bite of the brass without compromising the sustain or overall character of the bass.
