I’m custom making furled leaders for fresh and salt. 5 1/2 ft, 7 ft or 9 ft; 3 wt to 10 wt, Uni thread, fluoro or mono.
Shorb loops in each end for loop to loop connections.
$5-12 depending on what you want.
There is nothing - absolutely nothing- half so much worth doing as simply messing about in boats. Kenneth Grahame
