I am about to start a project to build a stand for a HDTV that my wife is getting me (us) for my birthday in a couple of months. The stand will be surrounded by an existing entertainment center and sit on carpet. I need to be able to pull the stand and TV out as a unit for access to wiring. Which style of caster works better on carpet - twin wheel or round ball? I am looking at these choices:
