I have not done a rescale yet, but want to say this. some guys end up balancing heavy blades by using very large scales, I don't think that is necessary. use a heavier wedge, or a larger wedge. I have a big razor with synthetic scales, which I'm guessing are lighter even than wood, it balances great but they are perfectly proportioned and don't have a blocky appearance.

just my 2c on aesthetics.
