Sorry I missed out on this debate, it looks like It was a good one. I've used both your approaches in the past and then decided to create one that satisfied my own needs, a system that uses triad shapes that enables you too improvise with all 12 tones at any given time, I call it the triad method. I spent about 5 years working it out on paper an utilizing it in my playing and teaching, I finally got around to putting it in a book format about a year ago but have been unsuccessfull in getting it published. All the publishing companies I've sent it out too were very impressed with it but said they probably wouldn't be able to market it and make any money, the sad thing is there probably right. Now if I would have called it the Learn To PLay Like Kirk Hammett Method that would have been a different story. Again, sorry I missed this debate.
