All nice blades, have used Tenyru and Forrest, loved my Forrest blades. I would go for one of these, as soon as the makers can guarantee their blades are designed with consideration for the dust collection of Festool. And are the same exact measurements as the Kapex blades. The way I look at it: the Festool blades are not throw-aways, they are really nice blades so why change. They can be sharpened..AND.....They are allegedly specifically designed to work with the dust collection system; so until then I stick with the Festool blades. I admit, I am not in love with the 60 tooth blade that comes with the saw, but thats not because it's crappy. I just have a preference for higher tooth count blades. A ZCI solves any issues I have with tear out.
Unless the dust collection design thing is some Myth whispered to me from the Festool kool-aid guy. Shane can validate how true that is.
