The BBZ-1 Rat 25 was designed by Pro Angler Bill Siemantel who has this to say about the Rat 25:The importance of showing the fish something new is critical in fishing. Having the fish-catching capability and performance with size, action and depth with that lure you use is just as important. Already proven in the larger BBZ-1 Rats that cover the top of the water column, the new SPRO BBZ-1 Rat 2.5" will change what you think about fishing rodents subsurface! Even though the BBZ-1 2.5" is a smaller version of its larger family members, this baby packs a punch!Gamakatsu EWG short shank # 6 treble hooks.
