Donny, I don't like furled leaders except nylon mono furled leaders for skinny grass salt fishing with a floating line and a dropper fluoro tippet.
I'm talking about these H&H braided butt leaders
https://store.hookhack.com/Braided-Butt ... o/HHBFT94/The reason is hardware - with nymphing, you're fishing multiple flies, adding split shot (a granny knot to hold the first one), maybe taking a needle and sliding an Otter's milking egg and bare hook before tying on dropper tippet.
The braided butt charged with mucilin floats, keeps your fly line tip from swamping, functions as a strike indicator, and perfectly drops your knotted leader segments like a hinge
(but doesn't cast like a hinge).
If the braided butt begins to swamp you can strip it through a chamois, and it's high and dry again.
You're going to be making knots, you may want to clip your complicated rig and loop it for next time.
You get miles from these leaders by knotting in new fluoro segments.
If you want to fish shallower and add a Thingamabobber strike indicator, it stays pinned on your segment knot.
the fish is on the bare hook from taking the otter's milking egg (which then slid up to the split shot)

took this on the size 22 midge about a quarter mile upriver (it's 27" and 8 lbs)
