We have a BLW (LI'L Rocker) hitch which is a 4 way like yours and I used to run with it locked in the 2 way swivel but it's harder to unhook at a campsite that has uneven ground so now I run with it in the 4 way swivel mode. It's quite common for the hitch to bind if it isn't sitting level, so you have a better chance of it not binding if you just let it swivel 4 ways.
