How Very Very true,
You spend hundreds or even thousands on your gear.
A lot of time and effort planing and getting that bait or lure in the water.
All is not worth Jack if you do not have your terminal tackle tied correctly.
Next one to keep an eye on is frays or nicks in your line, If it isn't perfect redo your rig.
That next fish could be the fish of a life time!
