The R41 is no more a rigid design than the typical EJ head. They both support the blade in the same way and the same amount.>>
Mike - I'm not entirely sure this is correct, not the R41 with the Yintal cap. I don't have massive magnification, but with the magnifying glass I have the blade appears to sit on the top of the combs which would make it very rigid. That is, the blade is either sitting on the combs or fractionally above them - it's very close and I can't really see. The razor feels pretty solid in operation - no complaints about wavering blades with this top cap. It's a different geometry. You'll probably say that if it touched the combs it wouldn't cut, but it's actually very efficient - and also smooth.
