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.

Gamma Edge 6 lb. It has the thickness of 8 lb. I've gone through a lot of leader lines and this Gamma is the best I've used. It holds up to zebra mussels and the busted up concrete that I fish in Lake Michigan quite well.

.010", .012" and .015" diameter monofilament. (nylon, fluorocarbon and fluoro/nylon copolymer. I'm not convinced there is a significant enough difference to affect my fishing.)

Cortland Top Secret tippet. Technically it's a fly line, but IMHO, it's better than Seaguar gold.

Seaguar Pounce is the most durable/versatile of the Seaguar leaders; Gold is the most supple (best for open water), Max is the most sensitive, but stiffer than Gold.

I use Maxima Ultragreen. Has been my favorite leader line for years. Very popular in the Northwest.

Ultragreen here too, been using it for as long as I can remember.

I’ve been using Seaguar Blue Label and Pounce lately. I like the Blue better in the brush, seems to take a bit more abuse.

25lb Yo-Zuri HD Fluorocarbon leader

I use a lot of Invisx for braid to leader. Offers more stretch but also holds up well. If it gets scraped up some, I don’t always think about retying. Knot strength is high. Value is great. For topwater I like big game.

InvizX is my go-to for leaders....hasn't let me down yet.
