Bauer, I see you've managed to track me down. LOL
Very high fat diets are better on a drug cycle because they are a great source of Cals. The drugs will ensure that most of this energy is used for muscle growth rather than fat storage.
Q2. Some people have a very hard time storing fat (or putting on muscle) for their entire lives. These are the people who can pretty much eat what they want without any fat storage, and are also the people who benefit from eat a whole pizza at a time.
As far as freedom goes, a huge guy like yourself has a lot more freedom with Calories than someone with less muscle mass. Then again, you have LESS freedom, in that you NEED the Cals just to maintain your current weight.
Q3. The comment about not eating a super high fat diet was mostly for people with less experience. You know your body better than anyone, including how quickly you gain fat (and from eating which foods).
I'd say eat more fat than normal, far more protein, and then the rest of your Cal requirement made up with carbs. Don't forget that you shouldn't be eating strictly "junk food".
