Very easy to pour, the Mad Dad Craw is an "action" craw. It provides a realistic profile when pitching, however, the claws flap like crazy on retrieve. If you're a fan of active claws, you will love the action this bait provides.
The MD3 SC (Super Chunk) was specifically designed as a jig trailer and has even more claw action than the regular Mad Dad.
Using an open pour is a great way to do custom work, finish off that last little bit of plastic left in your cup, test new colors, or introduce someone new to pouring their own baits.
