Impact Shock 2.5F Squarebill is simply the best for all species. The water exploded on my very first cast which landed a very nice largemouth bass. Later I brought in a huge northern pike and a salmon with very same lure. Sadly, I lost my first shock 2.5F. However, I have since bought as many as I can so I am well stocked. Thank you Lunkerhunt for producing a superior product.
