That's what I've done and it works like magic. But right now my customers can see the weight properties of a given order at checkout and I just don't like that. For instance, when you order a product and go to checkout, you can see the text "Table Rate (1x0.25kg)". This can be seen in all three phases of checkout.

I tried changing various things from admin but they didn't seem to have much affect. Is there a way to hide the weight properties from customers?
