Chuck,
Thanks for the info.  I'm just going with what was on the boat when I bought it --- with only a 27lb plow/CQR anchor (Kingston K27) I can't imagine I'll over stress the 5/8" line --- but given there was 200+' of line already in my bow anchor locker all I needed to to do was replace the rusted chain and add new shackles.

Looking online (Mantus Anchors and the Kingston anchor site) - they recommend 5/16" chain and 1/2 or 5/8" line.

I'll have to check how well the line clips into the foredeck cleats -- never tested it!

Mark,
Sounds like you are building a hurricane proof anchoring system?   5/8" nylon is hard to get onto cleats smaller than 10".   Just sayin.

Following Chapman's, I tried 5/8" docklines and found I could never get them over my 6" and even 8" cleats.  I use 1/2" nylon three strand twisted for lunch hook and 1/2" stretchy double braid for tougher situations.  36' and 11000#.   Gave more than 200' of 5/8" nylon docklines to my brother-in-law for his clamboats.

If you are committed to your present system, you should check out Wichard for amazingly strong schackles in small sizes.  Their SS is the strongest.

Needed to replace the chain and shackles on my anchor - the existing
shackles needed to be cut off with a cut-off blade (totally corroded).

Bought 16' of 5/16 galv chain to add to connect the 27lb Kingston plow
anchor and the ~250ft of 5/8" rode.
But I was surprised to find that I couldn't fit the U of a 3/8" shackle
(or even a 5/16") through the 5/16 chain.  Everything I read said I
should bump up the shackle one size from the chain to maintain working
strength - but given I couldn't fit the ends of the U through the chain
links I had to use 2 shackles on the anchor --- one with the pin through
the anchor and a second shackle reversed with the pin through the chain
link.

Is that normal?  I tried chain a 2 different locations with same results
