Depending on where you are fishing. The benefit to fishing trawls is you might be able to grapplem them up if a barge, tug or sporty cuts you off. I've actually fished trawls blind (no bouys or sneak bouys) in some heavily traffic areas. No one ever knew their were pots there. We also didn't use any of that fancy bridle stuff, but instead tied to the corner of the pot where the funnel was if it was a side loader. The thinking being that anything entering the trap when it was hauled would be pushed in. You want to use one main line with sinkline under the bouy and float line from the trap. The leaders to the mainline were lighter maybe 5/16 or 1/4 and a different color so we could tell the difference if we had to cut a tangle. ( They do tangle). Sometmes a 10 pot trawl would come up in 50 feet of line.
Knots: the leader was tied to the mainline by making a loop in the main line then doing the rabbit out of the hole around the tree twice and back down the hole. When you tightened up there was less stuff swirling around in the tide.
End of the season cut the leaders from the mainline and let them stay with the pot. Coil the mainline as was stated into a fish box. What ever you do don't let the bug bite you
. I spent a long time chasing those critters arond from LIS to off the shelf. Pull the traps in September and get back in school.
