The 2.5mm (7/64") Amsteel is fine for trap lines. Just be ready for it to have some initial stretch. My a-cat lines stretched about 4-6" before taking a final set.
Jake how many sails and how many times did you adjust before it locked into a range +/1 1/8 of stretch (ie Final stretch point)
It didn't take long. It was done stretching mostly after the first day. It was a good day with 12+ winds so I was on the wire most of the day. That evening I remember looking at it thinking "crap, that stretched a lot" and I had to resplice it.
