"Doesn't the Byrd head require more power?"

I've heard that it does but seen no documentation on it. I suspect that the RMS power requirements are similar between a spiral head and a straight blade head. Straight blades probably cause a high draw for a fraction of a second followed by a much lower draw until the next blade hits. Spiral heads are more consistent, having a small section of blade in contact with the wood at all times or close to it. So the power vs. time curve of a spiral blade I would expect to be flatter, and a straight bladed power vs. time curve to be spikey. But I would expect the average of each over time to be roughly the same for similar cutting conditions.
