Re: having trouble tying knots with lead filled rop
NGT, What type of crab pots are you using (square, house, round).
That leaded line is usually 5/16" or 3/8" for the commercial pots. It is more ridgid than the poly but you should be able rig the pots with a fishermen knot.
One thought is they sell a 4-way crab harness that has 4 clips to the pot into one single ring where you clip(caribenier) onto your line.
BTW hows the crabbin in your area? Here in Washington state the crab season shuts down on Sunday(Jan 2.)
Have a happy new year
