Yeah I got a pair of those Grr rippers, for my cms table saw since there's no standard feather board, and they work great. Although I probably will still make some sort of feather board at some stage too, just gotta work one out. I was told by a Festool rep to use a ripping blade rather than the high tooth blade to help it prevent wandering off the fence. I put in the 28tooth blade for crosscuts and rips, seems to work well but doesn't give as smooth a finish edge as the higher tooth blade when I cut hardwood through it.
