Hi Matt,
So the line from the bottom of the mooring ball is leading to the anchor?  I like to use all chain with a shackle and swivel at the mooring ball.  It it somewhat controversial whether to use a swivel or not and where to put it.  I like to put it at the mooring ball because I can inspect it and replace it relatively easily.

I’m surprised the owners of your mooring field don’t have their own rigging guidelines.
