kings and ling can be landed on light gear i have done it many times on 14pound mono...
have been planning on doing it with a 4000 shimano spinner with 300yards of 10pound suffix braid from my yak(i usually use 40pound suffix performance braid)...i'm sure yall will hear about it if i can make it happen...
a curado will work but you may get spooled, i always say you aint lived till you been spooled...good luck
have been using 56(coffee color) and 69(silver color) pound single strand tooth proof stainless steel wire with out any leader fail..the 69 pound wire has held up to a 100pound wahoo(and three kings over 50inches) and a 400+pound bullshark for me this year
I guess it defeats the whole "line class" angle, but I use a diawa exceller 3500 spooled with 50 lb cheapo power pro braid, mounted on a 6' med-heavy fenwick inshore rod. I did land a decent sized king on this rig, about 15-20 lb fish. He screamed drag for a bit, but petered out fairly quickly. I didn't have the drag cranked down terribly hard, but probably more than what 12-15 lb mono would bear. It was definitely a fun fight.
