Hey Superfriend, I would go w/ what works for you. Every person has a different physiology and responds differently.
As far as your dad, you should know that lipitor is poison. I was on it for 8 months. While it did lower my cholesterol, I had terrible leg cramps and it really negatively affected my mood. I have read annecdotal reports of people getting liver cancer after years on lipitor.
I have more or less natural means to keep my cholesterol under control as follows:
Niacin (flush free)
Low carb diet
