You know in the end is another tool that has it purpose... under the right conditions, they just catch fish. Suspending models do shine under cold front conditions though...

i do agree, they catch fish.but what are the perfect conditions for a jerk bait. water temp,weather conditions,wind blowing or calm,exc.......

If we're talking suspending bass, early spring, windy... that's usually a great time to pick one up. Water temps vary but 50-55 degrees would do just fine. I think water temp just dictates the speed... the colder it is, the longer you let it sit. But you know how bass fishing is, there are certainly no certainties!
