OK, I was wondering in your opinion, for those of you that have both, How they compare as far as the head, aggressiveness, and the overall shave. I understand the aesthetics of the rhodium plating, the 66 being heavier, the knurling, but maybe a side by side photo or differences in heads if any. Thanks in advance Phil
I'm pretty sure the heads are the same and they shave me the same. I much prefer the grip of the 66 though. The 66 was just a fancy HD, I think.
