I have used it, and as you say its very fine, so i bought 25lb BS, its very supple but when i paired it with my fluoro as in a combi link, i found that it cut my fluoro when i did a knot strength test. I have paired it with other monofils and it has been fine.
Because it cut my fluoro and the indifferent results i had for my knot strengths i dont use it any more, except in flood conditions when i can pair it with some mono of equivalent strength.
This is my experience with the braid, it might work for you and in all honesty i wish it had worked for me as i thought its properties were very good. Give it a go otherwise you will never know.
