Check out K-Labs ( http://www.klabs.co.nz/shopdisplayproducts.asp?id=13 ) and try their FluoroCasting line from Asso.
It is Italian line and brilliant. I just bought, Salmon line, Double Strength 15lb (.37mm) and 6lb Super HT, High Tenacity mono for all my Trout reels and trolling reels (.26mm).
I have been using Asso for several years now and wouldn’t change.
Value for money and harder wearing than most on the market.
