I've done a lot in that dept. As a fly fisherman I was using some very expensive flourocarbon tippet material. Eventually it came out on large spools. I continued to use it the same way, as a leader only. Because it has high memory and is expensive I use a grinner knot/uni-knot to tie the 2 together.
These days I have been using Stren low vis green(works as good)until I don't have to buy diapers anymore.
