What types of crankbaits do you guys like to throw in saltwater?  I will be fishing for speckled trout and redfish.  I have a bunch of suspending twitch baits, hard jerk baits, etc... I am looking for some lipped or lipless crankbaits that I can fish using bass type techniques.  I typically use whatever bass crankbait I feel up to, but they are not designed to withstand saltwater and tend to corrode.  Any help is greatly appreciated.

For blues and speckled/gray trout on light spinning gear, I use Mirr-O lures.  I have a few in a range of shallow to deep runner.  They work great.  

I was recently fishing for speckled trout and talked to some guys down in charleston the best thing was a fluke type grub in electric chicken w/a jig head. And also some D.O.A Shrimp in white color are really good for speckled trout.

I have used the Silver Buddy, which is kind of like a crankbait, with success on Sea Trout and Bluefish in the Chesapeake.

I used to do good in Sebastian Inlet with Rebel Windcheaters and Saltwater Husky Jerks.
