Attract. Enrage. Engage. YUM F2, or Ferocity Squared, is a highly concentrated natural formula clinically tested by the Mississippi State University under the strictest scientific conditions. The result is documented proof that bass prefer YUM F2 by 30 percent over the leading attractant. Additional advantages include its ability to be infused in traditional soft plastics in any shape, as well as long-lasting effectiveness and continuous dispersal of scent (no need to “refresh” every six casts!). Six bait styles are infused with this powerful scent, and unlike other attractant-injected baits, YUM F2 infused lures retain their suppleness and “swimability” no matter how many casts you make. They also don’t dry into hard, wrinkled and useless shrivels when left out of the package.
