Check the thread just down a little bit “Braided Line”. Seems everyone who suggested 832 is running 6#. At the very end of that thread there is a link to a list of all the braids and their test results, I think 832 6# broke right around 21-22# which means its comparable to 10# power pro.
10# 832. No reason to go any smaller, diminishing returns. Alberto knot is the best. A lot better than uni to uni knot. Thinner and goes through guides easier.
