Wrench said a mouthful right there. Now I'm not about to say a guy shouldn't attempt to learn as much about his prey as he can, but there comes a time when you gotta go with what your gut is telling you.
I remember a Central Pro-Am fall event on Table Rock quite a few years back where I had a decent first day and landed somewhere in the top 10. The second day, the wind died and I figured my best bet was to lay down my blade and go to a jig. I dragged that thing for hours without so much as a bite, and finally just the smallest puff of a breeze started blowing. My gut was screaming get your blade back out, so I did and within 50 minutes (what I had left to fish before having to head back to the weigh-in), I had a small limit and cashed a check.
You're just gonna fish better when you believe in what you're doing. If you're going against your gut, it's an uphill climb.
