Knothead, could you elaborate on what you use for locking the line?
I just grab a loop in the line, bring it under the d-ring and snap in in my spring hook. Bring it back under the d-ring and tie it off with a couple of hitches.
There isn't much load on it.
You can grab the 6 parts of the tackle in your hand and hold yourself.
You will have to figure out a way to tie off that you are comfortable with and do it that same way every time.
