I just installed a shark guard with the riving knife on my 2000 Grizzly G1023. Of course this decision was made after it tried to throw a piece of 3/4" plywood about 2 ft. square back at me - the edge split the top of my left index finger at the knuckle - no stitches. The riving knife would have helped, but I also think the fence was not set with toe out (actually toed in) which I found when I lined up the blade and the riving knife. Still, this is a much better guard system than the overhead guard I made out of aluminum. Dust collection is much better.
Thank you,
