Interesting. But, I think you need to experiment some more. Cutting a straight line is important, but probably the cut most scrollers spend the least amount of time cutting. And speed is not always real important, at least for us that do not sell at shows and such. It would, to my mind, take a lot of tests to determine chart-wize the best blade for which type of cut. There tight turns to worry about, type of wood, thickness, size of kerf, cleanness of cut, the list goes on. And, it all boils down to personal preference.
I've been seriously scrolling for over three years now, and I have finally convinced there in no one best type, or brand. Of blade. I am still experimenting as I go. I do stick, at least so far, with what I feel are probably the top three brands, Flying Dutchman, Pegas and Olson, ( I really haven't tried Olson scroll saw blades but I have used their other blades). I guess I need to throw some PS in the mix now. I use several different blades on one project depending on what part of the project I am cutting. What is becoming more important to me, is how to organize it all!
This is all why I shutter every time the question is asked, "what blade to use". To me it is the most confusing part of the scrolling world. I agree with you, people should try and experiment with other types and brands, and yet maybe not. If they can accomplish what they want with what they are currently using, maybe they reduce the confusion, and don't go around scratching their heads, mumbling to themselves, like I do, if they just stick with it. I had hair before I started scrolling!! But tis a hobby for me, I enjoy playing around and trying things. I could not just keep doing the same thing the same way all the time. Nothing wrong with it, just not my cut of tea.
