I've been scrolling for a little less than three years. The first time I tried the MG blades they cut so fast they scared me. However, getting a little more experience my mostly used blades are #1 and 3 MG . Most of my cutting is 1/2" stock and 1/8" and 1/4" plywood.. I have a lot blades I will never use. Occasionally I use #5 or #7 when cutting 3/4" Pine.
