You should measure the current rotor that you have. NovakTwo can correct me if I'm wrong, but it is very possible to get rotors over 1300 without getting the "graded" rotor.
It is also possible to have a 1200, but not likely. If you have a 1200, the 1300 will be better - you might be able to see it on the track (more likely at the end of the run). If you have a 1285 right now, you probably wont see anything.
There is some discussion about how having too strong a rotor in 17.5, I haven't raced any 17.5 single cell to find out. I don't think it is 1300 though :-).
