The ultimate thing about fishing is that your terminal tackle must be tip-top. Or you'l learn a very expensive lesson later on.
What I'm saying applies to lure fishing.
I have had the opportunity to experience this myself, even though I was confident with my terminal tackle and line ties.
I recently bought a Japanese snap called the "Egg Snap" and even though it was rated to withstand up to 30lbs of pressure, it broke open after i tried freeing my lure from grass near the bank!
Japanese products are always related to quality - or so i thought. With this bad experience, i would go back to using the snaps that I'm used to - RM2 per 10 snaps.
