Your right... all it takes is one...
It's really nice when that "one", is a "big one".
When it comes to live bait... the big baits catch big fish.
I've had big peacock bass grab 12 inch peacock bass I was trying to land.
A 6 or 7 inch tilipia struggling to get into the grass attracts some nice size preditors.
And all that action happens just a rod length away... right on the surface.
Just takes time and patience... It's hard to stick with a big live tilipia when those 2 pound peacock bass just swim up and look at your offering, asy: "that's to big for me." and turn away.
You might not catch as many fish using big baits,
But the ones ytou do catch will be BIG.
