Seller I bought from is Countbassfishing. He has the coffin shaped blades that measure .51 wide X .58 tall for the small size, and .64 wide X .78 tall for the medium.
I have high hopes for my Poisontail Swing Chatterbaits this summer. I cut notches in my mold with a die grinder, following the vent groove from the edge of the mold to the eye. The notches accomodate the blade, so I don't have to cut the wire. Blade is attached before casting. Works great.
