I have the Nodachi OC head and the Colibri 1.3 OC and SB plates. I find that the Nodachi has some, but rather small amount of blade feel and the Colibri plates hardly any. Efficiency-wise they are about on par for me, although the slight blade feel in the Nodachi makes it a little easier to keep the angle. With either Colibri plate, I can whip them around without much worry.
