I consider myself a 'thinking' fisherman but with nowhere near the same depth of thought and observation as you, Steve...
You have given me cause to rethink a lot of the things I do and I thank you for that. My approach to many fishing situations will change dramatically.
I also agree with Scott on the stealth issue. Last time I was snapper fishing in 1.5m of water during a hot bite period, I pulled the hooks on a fish close to the boat. The lure slammed into the hull with a loud 'bang' and I didn't get another touch for around 20 minutes. I figured I spooked every fish in the immediate vicinity and they only came back after a period of continued stealth...
Cheers
