There is a new line coming out soon and it is called Berkley Nanofil. Supposedly this is going to be the line of all lines. It is going to be super round and super thin. Will it be marketed for spinning reels? Initial reports is that it can cast a mile. It looks white on the spool but clear off the spool. I can not wait to get my hands on this new line. I have read that it will be available in June. Read the article that I read about the line here.
