I've never been a fan of wire leader, the pre-made ones are big and clunky. I'm pretty sure they adversely affect my catch rate for bass on the waters I fish in Michigan that are pretty clear and connecting the snap directly to a hook or jighead is awkward. At the same time, making my own leaders has always seemed hard.
Fishing in Florida the last few years has presented a challenge in this area as the salt water fish in the clear water are definitely line shy. At the same time, cudas and mackeral have much sharper teeth than pike. They can and do cut through 30lb fluro like it is nothing.
This year I decided to try the knot2kinky tieable wire to tie up some small 4-6" leaders using 12# wire with 1/0 hooks I use for live shrimp on the one end and invisi-swivels on the other end. It worked out great. The leaders were really easy to tie, just do a standard 5 wrap cinch knot on both sides, pull tight using a pair of pliers. On the performance side, my knots held well, the wire didn't kink much, and fish didn't seem to mind. It is a much stealthier presentation compared to the pre-made store bought leader.
This year I intend to try it out with some jigheads I use with Keitechs when I fish clear waters with combination of bass and pike.
