I suspect that there will be an increase in frictional force as the
contact pressure goes up and the tendency to brinnel the surfaces
increases. And there may be additional wear. But if you'v ebeen getting
satisfactory service using a rod, that's all that matters. And if you do
have wear problems you can probably go to a rectangular bar without there
being much on a problem with water retention.
