This is a good thread, here are a few of mine.
When transporting your rod after you've rigged it up to fish, hook the fly on the guide above the stripping guide and loop the line over the frame of your reel. When you are in position to cast again, just take the line off your reel frame, smack the top of the rod handle with your hand and the fly will drop onto the water with enough line out of the tip to begin casting.
For streamers on sink tips:
Roll cast before begining your first back cast. It wont feel like trying to pull a brick out of the water. Also, learn the Snap T and Double Spey casts
For packs and whatnot:
Tape down your excess strap materials after you have adjusted the pack to fit you. Less stuff for line to get snagged on, and it wont loosen up.
For casting flies under cover:
Side arm cast low to the water and skip the fly off the surface under the target cover like you are trying to skip a stone.
When casting down stream to cover:
Stand in the middle of the stream, cast to open water upstream of the target and throw a huge mend in the direction of the cover, the fly will swing into the covered area. When you need to pick up after the drift, mend towards the center of the stream and the fly will swing out of the covered area.
