Re: Scientific Anglers L2L
Yes, you can do that. Anywhere in the butt section of the L2L leader you can clip it off, tie a perfection or double surgeon's loop, and connect a leader via loop to loop connection that way. Cutting it off 2' from the connector and then attaching a 9' leader gets you an 11' leader that would work well on spring creeks and the like.
This is also done by those of us who have the L2L set-up on our line but have only other manufacturers leaders on hand while fishing that become needed. After you've done this you will still have the subtle strike indicator function of the L2L connector, but you can attach anybody's leaders to it via loop to loop.
