Very nice looking pike! I think that some of the smaller pikes mix very well with geo's, as long as the geo's are too big to be eaten.
And he has some awesome spangling!
I am also leaning more towards saxatilis vs. lepidota, solely because of that humeral blotch. The lepidota I had had a very nicely defined, circular blotch, whereas yours is pretty irregularly shaped.
Regardless, a great pike. I'm sure you enjoy having him a lot!
