The Rocna is a great anchor, thoroughly proven in the real world, and extremely well suited to the Bahamas. You see more and more experienced cruisers who anchor all the time trading out their trusty CQRs for them. Actually, "Bahamian moors" are a pretty rare sight. You can sit on a 3-1 all chain rig in most places.
Agree some sort of Danforth style, like a Fortress, makes a good stern anchor when backing up to a beach, or those times when you do deploy a Bahamian. Easy to stow, especially the Fortresses, but we use just plain old Danforths as the back ups to our Delta main.
