TOPIC: Question on EZ Loader

Well I am going to upgrade the trailer for the Uniflite. I just purchaced a larger EZ Loader tandem to replace the old SnoCo. The new one is a roller type and the old one is a bunk type. I have never had a full roller style trailer and I am not sure of the advantages and disadvantages. Any suggestions if I should switch it over to bunks or just leave it?
