I am a little late getting here but blade talk is my thing. I have more than twenty different size styles, and makes of blades. I do very small cut outs in large works. Wolf mini clock.
I seldom use spiral blades, but they do have their purpose. In fact every blade in my arsenal has its purpose although I only have two or three that are mainstays. It really depends on the wood you will use, the project, and whether you are stack cutting etc. I looked at those wolf patterns you mentioned. If I were cutting the clock of Steve's I would indeed use spiral for a lot of it. But not all.
I would use the smallest shark tooth I could find [3/0] depending on your wood and thickness. Perhaps an FD 2/0 Superior puzzle blade for parts of it.
So I would indeed go with a spiral blade. But I do think we all have our own preferences in cuts since many blades would work for much of what we do. We just like certain things certain ways. Spiral sounds good for that wolf.
