My brother fishes a LOT and told me to try the Nano so I did. He liked it but I could tell he wasn't in love with it. I hated it.
Did some research and bought Sufix 832 - LOVE it. I have changed all my reels over to it now and my brother is already changing his after trying mine.
For light line, they make a 6 and 10 lb. I am running the 10 for spinning and heavier on the baitcasters.
I run all my braids with a Flouro leader as well.
