cheezwedge,
I will send you a pair of used but fine
Omer BAT 20 blades for free, if you cover shipping costs. Of course, the lack of an appropriate angle is not ideal, but the stiffness grade should suit your physique and is OK for shallow water/medium depth hunting.
Here is link with some pics of the blade in question:
