Lee,
You should be aware that pike skin is going to dry in shades of grey. It will not even remotely look like the beautiful iridescent green/gold of the fresh fish. That's how come the taxidermy folks have to completely paint over fish mounts.
Cant say how many times I tried to avoid the grey thing. I believe it would be very beautiful, but trying to paint the beauty back in wont ever be quite the same. Hey but it just one old mans opinion.
