As stated above the wood non-billed Cracker works better as a twitch bait,for me anyways. The billed Cracker works better if you want to crank it or waked it.
Here's a couple links of vids that show the difference. The non-billed Cracker is my favorite top-water bait. Twitch ,slap,pop and a 180 turn,then kill and just wait for the blow up.
