I have been using the Freud Thin Kerf Glue Line Rip Blade - LM74R010 for about 3 years now and haven't noticed any deflection. I primarily use it on 3/4 - 4/4 red oak stock. It has been a great blade. (Probably due for a resharpening soon.) I also haven't seen a need for a stabililization plate with the blade. (Note: I use a Sears zipcode saw - 22124 w/1.75 HP motor)
Great blade IMHO.
