Why Nanofil, that stuff is a dog to work with. It is so thin that I couldn't get it not to dig in on anything except a couple of old ultralight spinning reels. That stuff snapped on me at any thought of a hard cast. I was using 15lb I think it was.
Try something like 832, or Power Pro, or Tuff Line, anything but Nanofil. You will probably get better results immediately.
I know a few guys that love that stuff, but they have years of experience with braids and do all the tricks instinctively.
As you get more experience with braid you will start using various tricks on the cast and thumb pressure, and drag control which will cut down on the digging.
Lifting the rod tip as the bait hits the water will help with slack line which helps with loose spool which helps with wind knots, and digging in when the wrap is TIGHT.
