Walking baits and poppers...try to find ones without rattles. 

 

Floating worm...

Are you target fishing, or fan casting an area?  The plopper, Jitterbug, buzzbait and spook are good choices for doing both. You can cover water, or target specific cover. With all but the buzzer, you can pause them. Even when fan casting, I recommend pausing and/or changing speeds. Once you get a blow up, you can adjust as you see fit. 

Next time you throw your Whopper Plopper try and land it soft, wait one or two seconds, then twitch it once or twice so it looks like a crippled bait fish. Pause a second or two, then twitch it again one or two times and then pause a few seconds. If nothing blows up on it start your retrieve (straight or stop and go).

 

I get a ton of blow ups on my WP's when twitching them after the initial landing.
