I completely get what you mean with the Series 8 head to head being perhaps the cleanest, but I think that the Series 9 head to head fits your exact description of "clean fight and then controversy happens afterwards". I also think that the fact that Ironside immobilised Pulsar in round 1 (as you brought up) should not be disregarded either.
