about 3-strand vs braided, I prefer braided because it is more chafe
resistant due to the multiple strands that support the line.

Yes, but doesn't the use of braided Nylon reduce it's ability to stretch?
We use three-strand Nylon and secure the boat using a bridle, not a single
line over the roller. I agree that roller will create an opportunity for
chafe. It also lengthens the arm by which shocks are transmitted to the
hull.
