Hello everyone, I'm new to this site. I am heading to Portsmouth Island in a few weeks, and have a question. I am new to surf fishing, and have been reading about shock leaders. I was on the island back in may, and used 20Lb test main line, carolina rigged to a 50 lb. leader, and had no problems, untill the blues showed up. My question is this, what is the purpose of the shock leader? i have moved up to 25 lb. test main line for this trip, with 50 lb. leader. Back in may, we did have a strong wind, and I was throwing 8 0z. at times just to stay in the water. Does the shock leader help with handeling, and throwing the weight? Seems the whole set up would be only as strong as the main line, when fighting a fish. If someone could explain the purpose i would greatly appreciate. Thanks, and tight lines!
