There have been a few posts in No.1 thread about this string but not a lot. I just can’t find much if any real testing data on it. Since I’m a big fan of thin strings and their characteristics, I thought it’d be best to have a separate thread on it so I wouldn’t feel horrible about going off topic when posting about this in No.1 thread. I’ve received a couple a packets today and here’s the front & back of it if anyone is interested in the “claimed” specifications or data. I’ll post more data once my 66um dies and I put this on. Another BC’er will be using one of these packets but at 26 lbs so hopefully there will be data ranging from all sorts of tensions. But right off the bat, this is the thinnest string I have in my box at the moment. Thinner than ZyMax 62 first & second gen, No.1, BG66UM, Pro 66 & BG66 but I don’t have any aerosonic around me to compare right now though I don’t think it’s as thin as that from what I remember. It looks exactly like no.1 and it’s almost as if they just made a thinner No.1. Has anyone of you tried it and liked it?
