If you're ridgeline is still loose enough for you to bend it then you're good. The problem arises when people pull the ridgeline taught before loading the hammock, which can easily occur on longer hangs. So long as your two trees are always close enough together and you hang at proper angles, you should never have issue with the ridgeline being too tight and therefore it should not break.
Mason line has a breaking strength of around 150#. Knots will reduce that to closer to 100#. In the past some here have done the math. Maybe a search will find it but I think the general consensus is a 500# rating for the structural ridgeline.
Works of art coming out of your DIY shop there.... Well done.
Good looking gear. I was going to do a search for how to calculate the size of your tarp skins, but my tarp is about the same size as your Kelty so . . . can you tell me your tarp skins dimmensions?
