I still see that link taking me to an article about Data Compression Double Take which seems different than SQL and T-SQL for Beginners or is that where it is supposed to link to?
EDIT - you also appear to have posted this in the future?
The above is all just my opinion on what you should do.
As with all advice you find on a random internet forum - you shouldn't blindly follow it. Always test on a test server to see if there is negative side effects before making changes to live!
