Another option is a copolymer line made by Gamakatsu. We use hi-vis 12# that has the appox diameter of #8 Maxima Ultra-Green(which is what we use for leader). Result is that we only break off mainline about once in every dozen times snagged(using 3/16 hollow core crimped to a tag end). The Gami line is extremely limp and has about 1/2 the streach of regular mono. Sportco can special order it for you, 300 yds for $7.
