That knot is very god with SOME brands of braid.
Others such as Berkley Nano it isnt worth sh^t.
we also have been using the Collins knot
but is also doesnt work very well with some of the slicker braids.
for me while a little bit to tie, the PR bobbin knot works with every type of braid. and it NEVER fails
here is the Collins knot
