There is more than one force at work and it is diffiult to beat them all.
If you allow ice to form all around your dock posts then the ice will have a secure grip on your dock.
If the ice shifts, you lose. If it pulls away in the spring as the lake is melting, you lose. As the ice melts it breaks up into many individual pieces and when the wind blows there is very little you can do to protect yourself if you are in an open area and an iceberg blows in.
People will have different opinions but it really depends on where you are located. It is almost like asking: What is the best boat? Everyone has a different opinion.
I have two aluminum docks that get raised in the winter. No damage. I have a wood dock that seems to get damaged most years despite the use of a circulator. There is no ideal way to protect your docks from damage but again, it depends upon where you are located.
