Having recently flown both the KR2S (mine) and test flown a basically stock KR2 (small extensions on the horizontal stab) I can say they felt the same to me. I honestly could not tell enough difference between them to say one felt any different than the other in pitch. My plane has outer wing fuel tanks and the KR2 I flew did not. As a result, the KR2 has significantly better roll rate, but I could not give you a degrees per second comparison. It was noticeable. Others mileage may vary.
