I use the Dorisea-uk site on ebay, and it has Agepoch, Dorisea or Saratoga brands, posdibly others, probably all the same though.
I will be looking to buy that in 8-strand and will be lokking to buy a high vis colour, I think, yellow, orange, green or possibly the multi-coloured one the do.
Fishing at night from the rocks I want to see where the line is going and currently I am on 30lb 8 strand in red (saratoga shadowstrike) with an 80lb 4 strand shock leader in yellow which works really well when you get the torch on the yellow leader when bringing a fish in. The red does disappear a bit at night though.
I might scrap the yellow idea and go for another contrasting colour.
