Well , I guess the proof is always in whether the lure actually catches fish for you.
For me, these lower cost versions of the original have -- leeries love them !
Interestingly , I took one with me to Denmark (family visit) and caught an amazing North Atlantic cod on my very first throw ... from the side , too!I was told that no-one had caught a cod at this spot in months if not years.
My choice of colour is definately the blue sardine look-alike!
