i use izorline platnium in 12# and use stren magnathin in 8-10# for leader. the izorline is a copolymer thus smaller in diameter and thus can get more on the reel. i have found it to have good abrasion resistance too. i have used ultragreen in the past and it is good line but i prefer the smaller diameter stuff. stay away from the chameleon though. too stiff for most baitcasters.
