If your pitching a jig, you have to watch your line from the time the jig hits the water until you reel it back to the rod tip. If your not watching with 100 percent attention, you have missed so many big fish you would cry. Stare at your line if you got a jig one. If you wont, sell your stuff and go bowling. Your missing probably 2/3 of the hits you get on a Jig.
Key indicators.
1. "sink" rate of your line slows, tear her head off
2. Line stops before it should, tear her head off
3. Ever so slight almost imperceptible "twitch" where your line enters water, tear her head off.
4. Jig feels mushy, tear her head off
5. Jig "disappears" and you feel nothing, really tear her head off.
Thats Jig pitching. Failure to do these things has most likely cost you a PB you never knew was there.
