Enigma, I am not going to disagree with you that TUT is a significant factor in hypertrophying the muscle. And generally, when you are working with a good amount of TUT, you are controlling the eccentric portion (thus overloading the negative and stimulating growth).
Personally, for myself, I've come to find that HIT (a la DC) works best for my goals, training mentality, and development. But this does not mean I do not believe in the principles of other programs as I've seen and trained other using more volume based approaches.
I look at it like this, there is spectrum where you have to be able to use sufficient volume, combined with a specific training protocol or level of intensity (I'm having trouble defining this, but I am thinking along the lines of stuff like forced reps, rest-pause, negatives, statics...in other words, the "special sauce" to a program) to create enough muscular damage and be able to train frequently enough to maximize the rest-recovery-growth period.
Generally, with more volume, you are not going to be able to train as frequently (some genetic freaks don't fit within this realm) and make consistent progress and with HIT training, if you don't train with sufficient intensity, then you are not going to create the musclular damage needed for growth. With HIT, you can train more frequently and have more growth cycles in a given period than with volume, but if nutrition is not on point, you aren't going to be able to use those growth cycles.
So what I feel it comes down to is finding the right balance between volume, intensity and frequency that works for you...and this takes time, experience, learning and a hell of a lot of hours in the gym.
X - You are spot on with the DC mentality, and with DC, it isn't just pushing out that last rep, it is getting that last rep and then holding a static until tears run down your face and your body starts to shake, then you know the muscle has had enough.
BUT I will not argue that DC is best FOR EVERYONE, just for those who fit the profile of someone with right mindset and physical attributes. In fact, I've told counteless people, NO, DC is not for you... There are many people who think they can follow the program and get results,,,sorry, this isn't color by numbers, just because you follow the program doesn't mean you are going to get the results. You need to understand and apply the training principles and be able to push past what you ever thought you could do, you have to turn yourself into a human highlight reel when training...DAY...AFTER DAY...AFTER DAY....
