We have used those in the past and fount that the 4" version #2364T2 work better.
And I agree that 2 wheel drive (75-80% weight over the drive wheels) and 2 ball casters gives the best manuverability for the dollar.
And when you want to 'stay in place' either drop a skid plate (anchor) or raise the ball casters with a cylinder or leadscrew.
