For pure knee shaking excitement, facing a school of tarpon with a flyrod has to rate near the top of any anglers thrill scale.
Nothing is quite as personal, it's angler versus fish, and all the advantages are with the fish.
One of the toughest concessions that must be made between guide and angler, is different angles of view provide drastically different sighting opportunities. Everybody wants to throw at fish they can see. Picking fish to throw at because they are easily seen, often leads to poor presentations to those fish because of terrible angles, while other fish in the school are perfectly positioned to be fed. I was set up on a ocean side white spot during horrible conditions a few years back. It was early and a giant school of very big fish started rolling through our hole.
