I've strung my 'fish with GHS Bassics, D'a XLs, DR Sunbeams, D'a Chromes, Ken Smith Nickels, and probably a couple others that I can't remember. I always use 45-65-80-100 or as close as I can get to that. I like the Sunbeams the best, followed by the Chromes. I also somewhat missed the zing when I went to flats, although i really would like to try the TI Flats since I prefer lower tension strings. They seem to have a lot of support here... 

we'll see!
