Depends on the individual bass to some extent. I use LaBella 760's on Fender P's and J's, but they don't really work too well on my skyline BG, whereas Chrome's do. I use Picato rounds (Pete used to fit these as standard to Wal's) which are probably the cheapest bass strings out there and they work well for me, so I'm going to try their flats and see how they go. Although the Lakland flats look like good value if bought direct from Lakland in the US.
