I have a popular one doing well in Fla., Texas and Puerto Rico.
looped butt - 4 feet of .025 blood knotted to 3 feet of ,022 blood knotted to 1 foot .020 and a perfection loop. 24 inches of 30 lb. fluoro with a perfection loop.
Loop to loop to fly line and also loop to loop tippet section. Change out worn tippets in seconds. I started this leader this year and with it becoming popular, I will have a card printed for insert! I see this taking off in a good direction.
As far as a "knockout" Trout leader, I would say, I would not promote this leader for Trout. Why? Simple, not enough sales. This would be as a custom tied for desired anglers.
I am marketing the above leader as a Saltwater leader. Many have contacted me with good results using the above leader on Redfish and Snook!
Global flyfisher is good. But remember they only supply leader formulas. A vast amount! But not much info on tests or performance! I guess my leaders are tested by fishermen with hard fact results! To put my leaders in carded packs, I must be 100% sure they outperform, outcast and outlast factory brand.
Started in 1986 and still building today! Son runs business now, I am retired, great! Easy year, this year, I figure on tying and selling a few for upcoming season. Hopefully, 5000 will be enough!
