I made the change to Jeppesen manuals before our masters mandated the change because I was thoroughly pithed off at the lack of service from the Publications Centre, and multiple pages of Notam corrections, and four whopping sets of ammendments per anum.

ASA might well have improved over the last 8 or so years but once a business has lost a customer it's pretty hard to get them back.
