Hi Pops,

Thank you!

Why is it that you prefer ball over wheel? is there less
strain when moving, leading to less failure?

-T

exactly, the ball type can swivel in any direction where as
the wheel type needs to turn so the wheel will roll
properly, if not it puts extra strain on the caster and stem
which in turn will wollow out the hole and you'll have
failure

That explains it. Thank you!
