Ill be seriously testing Sufix Nanobraid second week of April on Pool 4!
I was looking at my Gliss package and on their website. Gliss is manufactured by a German company called WFT and marketed in the US by Ardent. They claim the line is “100% HMPE FIBRE” whatever that means. I prefer Gliss over Nanofil but that is just my opinion in one season of use. I can tell you Gliss casts a mile with a flick of the wrist and is super thin. By no means is this stuff knot friendly though. I have only tried it on spinning reels.
I haven’t fished with Nanobraid and only looked at the sample strand on the box at Scheel’s the other day. It reminds me of a micro braid and might be more knot friendly than Gliss. Make sure you report back when you test it.
