Question: Have you used a convex leader before? How do they cast? Will they work well with loop-to-loop connections? David.
The JOURNAL ANSWERS:
Well David you nearly had me stumped, thank goodness for Google. Like most fly fishers, I’d reckon the only way I’d ever fished a convex leader would be unintentionally, adding too thick a transitional section
However I did find this reference to convex leaders from the book Drag-free Drift by Joseph A. Kissane & Steven B. Schweitzer. Or if you have a collection of back issue of Fly Fisherman magazine you might be able to find Bernard Beegle’s original piece on the topic in 1983.
Traditionally most leaders taper from thick to thin over their length whether you are buying knotless off the shelf or building your own at home according to the many recipies, or you own fancies.
Beegle, an engineer, believed that flyline design should also be applied to leaders, whereby instead of that consistent taper, a thicker transitional segment should be included between the butt section and the front sections, to aid loop shape, line speed and turnover.
Basically convex leaders are shaped like a weight forward flyline, which it seems to me, and the article suggests would make them better for longer casts, and heavier flies, rather than delicate presentation. But I hasten to add I have not fished these leaders.
I can’t see why these leaders wouldn’t work with a loop to loop setup.
On the other hand I’m also pretty simplistic compared to some in my leader setups. The only time I both with a fancy leader is tricky dry fly situations whereby I love the George Harvy drag free leader. Its a killer.
I hope this helps
