Hi,
This article gives a lot of info on low stretch leaders.
When the tapping stops
The main problem that I experienced was as a result of my casting action. I tend to use a circular motion which twists the leader and when the tension relaxes, say when changing flies, the leader furls.
I tried including a small barrel swivel between the braid and the mono but it did not feel right.
I also furled a 20 foot leader from corastrong but it still twisted on casting. Next experiment will be with corastrong and some flourocarbon furled together to see if I can eliminate the twist.
