What's the best braid for a spinning reel? 

I use KastKing Super Power on mine. You can get 150 yards on Ebay for under $5. 

Power Pro Slick8 and Nanofil are the two best lines I have ever used. They will outcast ANYTHING I know of and I have been told the Nanofil will out cast the Slick8, and I believe that may be true. I bought some cheap braided, and I found out why it was so cheap. I use it for hanging flower pots from my deck because it is like fishing with rope. Good braided will cut threw most of the weeds and comes in high visibility colors, like yellow, and white. Around sun set or early morning us old farts have a hard time seeing the Moss Green to tie knots.
