Re: Scientific Anglers L2L
The leader end of the connection appears to be molded or cemented on, so you couldn't add material to the butt section, unless you cut the leader and used blood knots to add some material. I'd think, though, if I were going to make my leader longer, I'd add longer tippet. That's why I bought the 5X leader; I seldom use 5X leaders longer than 9 feet. If I needed a longer leader for spooky trout, I'd also probably want a lighter tippet, so I'd add 2 feet of 6X or 7X tippet to the end of the 5X leader.
