Berkley XDS!! I use it, along with the 'normal' Berkley braid, for ALL my fishing. Instant contact with the fish, the softer spinning rod allows for taking the sudden strain of a diving fish rather than the line stretching. As long as you don't use your rod as a crane and the reel as a winch the thinner braid does not 'bed down' on the spool and retains its smooth outer covering. I use 17lb for spinning and light rod fishing and the 35lb on my beachcaster. I also have a second spool for my ABu elite with the 17lb with a shock leader for when i'm fishing clean beaches. Only been using it just over a year but see no reason to change. Also experimenting with some Spiderwire on a spinning reel (bought both cheaply on E-bay!)
I found some bits of a very smooth black braid (no stretch anyway) someone had lost on a rock and find it stiff and ideal as snood material. Anyone any idea, from my short description, what it might be?
