The Abare Dama or "Wicked Ball" from Zappu is an amazing little innovation. This was one of my favorite things that came out this year at the ICAST show and it was because it was so unique.
This little tungsten ball and screw adds so much action to the bait it is crazy. It is unpredictable and I think it gets a few more strikes. It's not something I am going to use all the time, but when you need something a little different it definitely stands out. Retail is $3.99 for two which is pretty pricey, basically you can add two dollars to the price of your baits. Other than that, it's a new look for your hardbaits.
