It's just really hard to catch a bigger fish in clear water. Yes, I could throw really small crankbaits in super clear water and catch smaller fish, but that's not what I'm after. Although jerkbaits are better at clear water than crankbaits, it's still difficult to catch big fish with them in very clear water.
Another topic I've always wondered about seems to always come up when I fish with Zipstick. I've fished with him a lot over the last 7-8 years and he seems to elude to the fact that the different species of fish seem to bite at different times. He will catch all largemouth from 9-10am then the smallmouth start biting at 1:00, or some variation of that. In my mind I've always wondered if it was just the location on the river where the largemouth spot was, or where the smallmouth spot was, not that the largemouth turned off and the smallmouth started. But he believes they turn on at different times.
