Would it be better to use the Leveling Plate Mounted casters or the Stem Mounted Casters? I want to purchase these leveling casters for a project and noticed everyone here has experience. Here are the two options I am deciding on. Just trying to figure out the best way to attach these. They might be over kill but I'd rather be safe than sorry. Thanks!
