I've played some of those Godins before and the noticeable difference (if any) is very subjective.
In any event, you can buy the routing template from taipan tone via the same link that was posted above.
I can see where more mass makes a difference on the sustain block of a tremolo, aiding in coupling, but on a string through type of tailpiece/bridge setup, there is already so much more transferrence of energy, that only an oscilliscope could tell the difference where human ears cannot.
