First of all, thank you for the nice comment on my project. As far as the #3 Pegas spiral blades goes, I really enjoy cutting with them a lot. I have found that I tend to have a lot of breakage with the #1 spirals, especially if I am cutting a large pattern with a lot of fine and small cuts. Because the entry hole is so small I tend to get the blades bent trying to put them into the holes and it causes the blades to get a bend in them. This, of course, causes premature braking of the blade. Using a #3 bade I reduce the amount of early breakage, as they are much stronger than the #1 spiral. So if I am able to use the #3 spiral, I prefer to do so.
