For quite sometime , at the suggestion of a helpful friend here (Tom - RIP) - I have been using Maxima Ultra Green leader wheels in 6lb - 15lb. (depending on application) . It’s a robust leader line , knots hold up well , it’s good for any depth - including top water , it’s low in price and virtually disappears under water. Seaguar Gold FC lable leader line would be on my short list to try and there may be other leader lines worth trying but so far I’m still satisfied using Maxima Ultra Green as a leader for everything with braid . What are your current favorite leader lines you are using with braid main line ?

Hard to beat Maxima UG, the standard for fly tippet and knotted leaders for more than a generation. I've also used their leader butt for tying wire-tippet leaders for toothy salt fish.

In fluorocarbon, Seaguar has always been the knot-toughness standard (along with Umpqua and FrogHair).

I use Seaguar Gold in 30- and 40-lb for surf leaders, and abrasion resistance is tops.

In lighter fluoro leader, I'm stuck on YGK V10 (soft and tough) and V12 (max abrasion resistance), and throw in Seaguar Grand Max in lighter sizes.

I also don't consume leaders by knotting lures (I knot flies), but put a perfection loop on the business end, to loop-on paper clips, micro-swivel snaps, and wire bite traces. I get up to a year life from leaders, which is a good test for toughness and abrasion.
