Re: Poppers?
For me, the secret is in the pauses between the pops. The bigger the popper, the more this matters. Remember, bass are primarily ambush predators, they like their prey easy to catch. If a big bug is moving quickly or often, it appears to be more alert and ready to flee. If the bug is moving just often enough to prove it's alive, it will appear to the bass to be more unsuspecting and therefore easier to catch. I've seen bass sit under a popper and/or follow it for quite awhile before deciding to eat it or not. If I can make myself leave the darn thing in one place long enough, he'll usually grab it.
If it swims and eats, it'll eat a fly.
