Re: Jumping fish
A good tactic I learned early in my fly fishing experience is to "give them the rod tip" whenever they jump - just drop the rod tip and stretch your arm towards the fish. This feeds just enough slack into the line that when the fish re-enters the water it's not as big a jolt to leader and tippet. Not sure there is science behind it, but I've gotten in the habit of it and rarely lose fish when they jump.
I fish, therefore I am - but I gotta go to work first..."piscari ergo sum"
