With all due respect to Phil and Dante, none of us have "created," nor do we own, any training "system".
Low volume, higher frequency, etc etc, even deep stretching, has been around for many many years. Neither Dante nor Phil have "created" anything except for their preference of a variety of methods. There are NO secret routines. EVERYTHING.... EVERYTHING has been done before.
When discussing training, you will learn more and come across better by mentioning and explaining every variable when asking about it or trying to teach others, instead of following a template with slight alterations.
Not really sure what you are trying to get across here...
I will say this though: there is a difference between a training technique and a training system.
A technique is a way of performing an exercise, therefore encompassing such things as rest-pause, sweet spot reps, bottom position reps, drop sets, and so forth.
A training system is a particular way of combining the various elements that constitute training: reps schemes, exercises and exercise selection, diet, rotations, and of course, a combination of techniques.
On the basis of this distinction, we CAN indeed say that Phil and Dante have invented training systems. Confounding the two, you have concluded otherwise. By an analogy, you would say that Shakespeare did not author Hamlet because he used the english language, which existed before him (although to his credit, he did coin some new words).
To the OP, lots of food and then either start with straight sets if you have mediocre recovery or go right to rp if you are on the moderate to good recovery end. You can add statics from there when safe. Remember that different techniques may be better suited for different bodyparts. For instance, your back width movements might progress well with rp but your chest doesn't, act accordingly. Above all, listen to the logbook. During my prep, I noticed that my straight set movements were going along nicely but my rest pause movements were not, this being exacerbated by the fact that my chest/shoulder/try recovery is worse than my legs (also a lot smaller, who woulda thunk there'd be a correlation, haha). Well, I asked Skip whether he thought I should try going to straight sets, and he said I'd be stupid not too based on what I was seeing in my logbook. I ended up doing two sets with the same weight, aiming for 15 reps to failure on the first set and then 8-10 on the second. If I started stalling again, I would have dropped it down to only one set, but as it happened, this was pretty much perfect for me, and I more or less kept beating the logbook until only a couple weeks out.
