I guess the title says most of what I wanted to convey.. I have a set of Rotosound 77's on my SX P bass and love the sound, but think I dislike the tension. They sound fantastic though. Today I put a set of DR flats on my Natural ash SX Jazz and, well....WOW! I love these strings! They definately sound fantastic, feel better to my hands and feel like a little lower tension than the Roto's. I think I will string my 5 er with flats eventually too. My Geddy clone may get half rounds or something a little brighter sounding for a flatwound. I want to try a few different strings to see what I like best, I'd hate to say the DR's are the one, but like them alot right now. Any of you have all flats on all basses? And if so all the same brand?
