A good read Mathew. Quite how this can be used I'm still a little unsure however, on one of the underwater Barbel DVDs I have it clearly shows a fish entering the field and viewing the bait with it's right eye, it turns around the bait keeping it in view (with it's right eye) before picking it up and getting hooked. Thus seemingly confirming what you have said.
Pesonally the older I get the more I like the concept of NOT thinking so much as to why, but just accepting it does.
Thanks for the article though, Mark.
