The Clay Hayes video is pretty good. It borrows a lot from Dean's original video, in terms of the form, and the general process. It produces a really nice bow, but it has quite a few differences to Dean's method. Admittedly many differences are style, such as a truly flat belly, and the power lam, which won't necessarily make a bow better or worse, just a different approach. I can't think of the name of the company off the top of my head, but they popularised this style of bow, and produced them for many years before giving the process away commercially and doing a more manufactured modern style of bow(perhaps with FG). They wrote an article about their original method in TBB vol4.
A combination of Deans book and video will give you a really good perspective on how and why he does things, which to me is very important, because you get to clearly see the logic behind it. They hold many more gems of knowledge, in terms of what variables you can use too. Its definitely a lot for a new bowyer to learn and understand, probably better for someone who has a few good bows under their belt, before delving into.
A perfectionist and a romantic, like Tommy mentioned? Definitely. Dean taps into the approach of the golden era of all wood bowyers, that delves a deeper than just getting a good bow that works. Its all about capturing the golden era style, and grace, the smoothness of form, of good design, and dare I say art. So definitely romantic, perhaps not everyone's cup of tea.
