Boot canting help needed. How to trimm tip and heel lugs?

[tdk6]

I copied the following text off of www.harbskisystems.com:
On all boots that are planed, we must replace the removed material thickness and make the toe and heel lugs parallel with the boot sole in order to return your boot to the DIN specified dimensions.
On most boots, we accomplish this by adding sole plates and then machining the toe and heel lugs. The plates are durable, replaceable, and come in different thicknesses.
Some boots have hollow toe and heel lugs (for weight reduction), and then cannot be machined. In these cases, we build back to the original thickness with epoxy on top of the lugs.

I am wondering how I should finish the installation of the sole plates after I have screwed them on. What method do you suggest? Does the Doberman 130 Pro's have lugs that are hollowed for weight reduction?
