Oh, and while you've got the neck clamped to test the alignment, check the neck angle is OK - another reason you want a flat neck. Run a long straight edge along the neck and make sure that it hits the bridge saddles so that they can be adjusted up or down enough (allowing that the strings will be 2-3mm higher than this once set up). If the edge is way over the bridge, or ends up below it, then the neck angle will need adjusting.
