Why and how to do a tercina
Ok, here's a good rig detail a lot of people don't know about, it's called "Tercina". It's a very simple thing to do but also very important if we plan to use powercasting or rig with very delicate nylon.
Basically its a line twist and a knot on the top of the rig that will attach to the clip of the spool line and why we do this? Because the twist acts as a shock absorber for impact when we cast. It has many advantages from the line not breaking to preserving bait on the cast.
It's so common to see surfcasters using strong shockleaders and then forgetting to make a "tercina" on the rig... then letting the whole thing break where the weakest link lies, the rig.
