On our recent trip to Bayou Teche, Foulcard and I used crankbaits almost exclusively, and switched to soft plastics around mid-morning, when conditions and terrain warranted.
Lures are expensive today. Jim Davidson, who also was rigged with a crankbait, offered us a tip to preventing snags on submerged structure.
Most crankbaits come with treble hooks. By clipping off the bottom hook on both the front and back trebles, it helps the lure not to snag or get hung up on submerged structure.
