I, also, am a braid/fluoro leader guy. I've tried the double uni and the alberto but still found that they "ticked" the eyes when casting. They also take some time to tie, especially when you break off a leader and have to tie the whole mess up again.
Lately, I am using two simple loop knots nested together. I tie one loop onto the braid, then tie another loop onto the fluoro. I then slip the fluoro loop OVER the end of the braided line; then feed the tag end of the fluoro down the braid's loop, and pull them together. No more "ticking". No more tying complicated knots with my arthritic hands while the is wind blowing.
When I have to replace the leader, I just cut it and pull it out of the existing braid loop. The braid loop may stay on for a month or more, with my just changing the leader loop and line. Strange, I know, but it has been working well for me. Kind of ugly, too. richg99
