As a big fan of HKC with FSK250 rail, I also use inexpensive CMT blades. I only reduce the number of teeth, 271.160.24H (160 diameter, 24 teeth), crosscutting even thick boards. When I cut plywood or OSB panels, I use the TSC55 (older generation TSC55 with 2.2 kerf width) with regular FS rails, if OSB I use a 24 teeth, if plywood I use 24 or 40+ teeth.
