If you fish waters like Montana and Idaho that are full of hungry trout and many waters that have NO pressure, the leader length might not matter. I have been reading about the LOCH style. The gentleman in the picture is a good friend Devon. I made these out of furled leaders and the tippet is where that tags are. Made it easier to roll cast it away from the boat.

In the latest issue of American Angler, there is a wonderful article of the benefits of the long leaders.

While searching however, I ran across this. Reminded me of the past post about "furling?" without a jig.
