I've always thought the fillies should have a TC just like the traditional one. I hate how almost all the races for females are 1 or 2 furlongs shorter than those for their male counterparts. (Sorry, the Kentucky Oaks and the BC Distaff at 9 furlongs is a farce) Just because they have 2 X chromosomes doesn't mean they don't want to run 10 or 12 furlongs.
