Definitely more than one way to make a good bow, even of the same basic design. A lot of it comes down to what suits you, and what gels with your way of thinking.
Dean's method is definitely prescriptive. It was what he thought was best. It is usually what is logical, and efficient, though. He also explained why he believed this to be so. You can understand his reasoning why he did what he did, which I can respect even if I know it's not the only method to achieve equal results. Sometimes the benefits are only marginal, or stylistic, I can see how that might cause disagreement.
It took me a while to get my head around his method. I like the results, but it's not the only approach to making an awesome bow., so I'm happy to use whatever method or combination of methods works best for me, on each particular bow.
Its always cool to see what other people think, and what works for them, when it comes to bowmaking. Just when you think there's nothing more to learn, someone comes up with a new or different perspective. There's not hurt trying something new if you feel like it.
