Gavin, Fireline is a good strong line but the tendency to 'fur up' making a horrible grating noise going through the rings makes it totally unsuitable for trotting.
Spiderwire is good but expensive, something with a tight weave is what's needed. Diameter needs to be something like 6lb Bayer perlon which will have a breaking strain between 15-30lb. Any braid rated at more usual breaking strains, 6-8lb will be so fine it's hard to handle and what with abrasion and the eventual true B.S. after knotting they're just too weak.
When the new braids came out, Don Neish did some extensive knot testing and found a knot that gave about 90% strength, but it's not really viable to tie bankside, a Palomar gives 70% and a grinner only makes 50%.
I'm using 18lb rated presently, so using a palomar, to a swivel, gives me about 12lb and I use hooklinks from 3-8lb.
I'll dig out the braid box and post up the brand later but if it's the right sort of diameter and doesn't fur up if you run a fingernail along it it should be ok. Ignore the stated B.S. I've got some on a fixed spool for spinning and floater fishing that's rated 30lb, not much thicker than the 18lb on the pin.
best of luck with it.
