I've been a pretty dedicated Cobra Classic user for the past three years or so, I haven't spent much time in the DE forum. I borrowed a friends R41 and used it for two weeks and I enjoyed the razor a lot and ordered one for myself. So far I've only used Shark and Kia blades. What should I expect with this razor? Is it too aggressive to use as an everyday razor? What are your favorite blades and least favorite blades in the R41? I've already discovered that I you need to pay attention when you use this razor unlike my Cobra.
