I was reading a dated post about using shock leaders with surf rods. The gist of the post that the surf rod could generate such force that if the sinker came off it could seriously injure people or property. Okay, I'm not a mental midget... I can see exactly what the thread was about...what I can't see is how would you tie a shock leader to your main line. The shock leader should be a minimun of 10 times the weight of the sinker... 5 oz = 50 lb shock. I normally fish with 14 lb test line, some reels go up to 20 lb test. So, I guess my question is what knot would a person use to join the two lines together so you can still cast? If knots do weaken the strength of the line, how much breaking strength will there be left after the knots are tied. I would much rather loose terminal tackle than hit someone with a 5 ounce sinker. Suggestions?
