Views: define sort order based on the weight assigned to the nodes' menu entry

Does anyone have any tips for sorting the order of nodes in a view based on the weight given to the node's menu listing?

I have already used CCK to define a field to give the nodes a custom user defined "weight" but it seems a waste of energy to have to define this rather than use the weight already defined for the menu listing, since that is the order I want to use in my view display. . .

Any help is greatly appreciated. . .

I'm new to this so I hope the question makes sense!
