Routinely? Yes every time I get a bass I always fit a new set of flats & that's it for a very long time.
I like to match my string to the feel of a bass - usually that's GHS Precision Flats 55 - 105 on a P-bass 1&3/4" neck. Status HotWire Flats 45 - 105 on P-bass 1&5/8" neck & TI JF344 43 - 100 on Jazz bass 1&1/2" neck. I love the Nylon Tapewounds on Fretless, GHS or LaBella, (Black or White), 50 - 105.
It's not a strict formula I stick rigidly to - but it works for me & I can't remember last time I replaced a set, I don't play as much as many folks though
