Thanks for the suggestions. LA Bellas have a good following for good reasons.
For years I only played Rickies and migrated from Rotos (one refret too many) to the Ricky brand rounds. (Sticking with one brand meant so much less work setting up new strings.)
But on my pair of Guild shorties, in recent years I always threw on TI Jazz Flats, but swapped one over to the Pyramid flats which sound almost as good and have a bit more tension on the right hand.
A long way of getting to the news that I went with what I know and put a set of Pyramid flats on the Performer today. Even before intonating the bass, it sounds so much better. I figured I'd put rounds on it, but so far it sounds wicked with the flats. May I say, really "Fendery?" I'll prolly leave it as is.
