Agreed!
My go to is FDUR #3 and #5 that's why I have 2 gross of them, and I've found a need for a spiral blade every now and then. My problem is that I have no real idea what else there is or how they perform, also I haven't found my nitch yet and I'm cutting anything from 1/8 to 1 3/4 thick. Plywood, MDF,hardwood and pine. So asking this question helps me look at other blades to try, plus a dozen blades here and there won't break the bank.
