You definetly have some old school stuff there.

I have a flexbait like the one you have pictured, just a different pattern. I acquired it from a guy at my work and he said it had been in his tackle box for years, he wasn't sure where he got it.

It's the early production run of the bait that Gregg Silks (maker of the z-plug) and a few partners of his designed. They only made a limited amount of them and made allot of changes over the years only never to put them back into production. Anyway, it's a pretty cool lure, Gregg said it's a killer trolling bait. I haven't fished mine much,it doesn't have much action except on a fast retrieve, which makes sense to troll it.

I thought I'd just hang on to it and see if it's worth something in the future.
