Hi, no offense, but what you did with the Tegu was forced handling, it should NEVER be done with a varanid, the stress caused will result in serious health problems (even death, in some cases).
I would use your advise as a "what NOT to do", rather than as a workable method of captive care.
The only way the monitor will learn the keeper isn`t a threat is by working at the animal`s pace, not the keeper`s!
