Daiwa J Braid x8 in 8# is hard to beat for that use. It's what I run when I am throwing something that needs braid. The 4x is a 4 carrier line, and is rougher, more of a flip and frog line. They have a new one out Grand, also an 8 carrier, but I didn't like it enough to spool any yet. It's slick and stiffer than the 8x regular. Several colors available.
That said, your trouble with FC might be due to spool size. 2500s are too small to handle it well, as are the new Daiwa LT in the 3000, or the Lew's in 3000ish. The Daiwa Black Gold and Eliminators still use the old big 3000 spools, and the Lew's 35 (saltwater) and 40 are ok for it. It also needs lots of line conditioner, as does the braid, really.
Braid remains a mess in wind, and it has some other quirks. It's not the almighty twirly reel solution folks make it out to be.
