My take on this.
I don't think it is blindly following advice if you know what you're looking for.
CT was at 20% BF and went down to 5%.
Bernardi was a skinny ecto and went up in weight and muscle mass.
I think you need to look at your own Somatotype when deciding who's advice to follow. Bernardi has great nutritional and training advice, but I wouldn't want to follow it for my body type.
Where as CT and Shugs have been in the same shoes as me and the OP and have dropped down to sub 10% with great success following a similar approach.
In the case of the OP, he's been at a high bodyweight for his height, and even though he's dropped the weight and could keep going, you have to realise that he'll never be able to follow the same diet programs as someone who's never been fat.
Chris Shugart wrote a very good article concerning FFBs. Whe I find it, i'll link it for you.
So while there are trainers that give conflicting advice, you need to realise that a lot have them have no first hand/personal experience of being in that situation.
That's why CT's advice has worked so well for me, in regards to losing fat and gaining muscle. But to the OP, there are so many articles for you read and implement on T-Nation.
