I just picked up an 11 pack from a popular auction site for about a $100 from the guy who I think is also the maker of this lure. Got to tell you, copy or not these are rock solid baits! LOL I did not even know they came with an extra tail with each lure and they look like they will fit the SPROs I have that need a tail replacement for my 2009 season. The tails alone would have cost me $55 (+S/H) from SPRO! Got it wet in the bath tub on a string and it sure looks like it will swim just fine. Little too much ice out right now for me to get them wet for real. Video he has showing them swim sold it for me.
