Seagur flouro works great for me, In the low summer time it will out fish mono big time. We've fished it the last three years, it takes practice to tie knots with it. I dont ever spit on it, dont want my stinky scent on my leaders. Instead always have a little bowl handy. Fill it with water and add a drop of lemon joy. The extra lube really helps when sliding the knot down on its self. You have to have lots of lube and go slow. But if you can tie a strong knot, flouro WILL up your catch rates. We've landed everything from big early season summers to huge late season winters with seagur's flouro leaders. If you doubt it's success just come fish side by side with me.
Also the best knot for flouro is the double clinch knot (trilene knot). Flouro is a thick line. Other knots just wont hold up to a fish.
