From what I read, the Red Label Fluoro is smaller diameter than other fluoro and mono. It is my favorite fluoro and all I use. Just like Ruger, I use 6 lb red label where I used to use 4 lb mono.It does take some getting used to. I don't go any smaller because I ain't got time to be using a net. I gotta boat flip them and get back out there!
I have switched a big part of my spinning rods though to braid and a fluoro leader tied with and FG knot which is really nice in my opinion. I even have it on my crappie rods at the moment.
