well, Bear started with a guy cutting his molds, that guy designed the original Kodiac. Bear started machining his own molds a while ago and redesigned the Kodiac as he is eventually going to phase out the original hinged molds. i have had guys say they preferred the K2 (new) bait over the original (got a bunch of the baits sent to me by a friend to try) Go with at least the 4.25, if not the 5"
