I don't fish furled leaders, I put floatant on my leader and tippet when using dry flies and don't if I am using wet. However I have been testing a braided line for my tippet that really seems a little better than mono or flo-carbon. The one pictured is made by STREN but I have some made by EZ brand Spider-Wire too. What it so neat about this line for tippet......it is braided and really strong. The one pictured is 8LB test line....but
it is a 3LB dia. line. It is also "nick" resistant (if it does get nicked, it doesn't loose all of its strength). The green color is just about invisable in the water. With this
tippet, every time I have hooked a "toothy-critter" (gar or pickerel) I have been able to land them without them cutting my line. The only down-side.......If I get hung-up on a stump or root, it is a little harder to break off the tippet. I mostly use this in the river and around lilly-pads ( If my fly gets caught on a lilly-pad, I can pull it free without breaking my tippet and loosing a fly).
It is made in heaver weights too, which I believe would make a great leader. I just bought some that is 30LB test and only 8LB dia. I plan on trying this as my leader and a lighter (mono, floro or braid) as my tippet. I don't like paying $2-$3 for tapered leaders and I have high hopes this braided line will work as a leader replacement. I will have to see how well this
heavier braided line "turns-over" when used as a leader, and how well it will float (with or without floatant). If you are a "purest", and believe you must fish a 7X tippet, this may not appeal to you.......However, I feel this stuff is really worth a look.......................Don S. in SC
