I thought all the models got a redesign at some point with that top cap!Saw these posts and it caught my interest. I notice that the +++ also seems to have a slightly more profiled face on the cap, which might lead to more available angles. Notice the slightly curved shape of the edge in the aggressive (dark grey), versus the straight edge on the non-aggressive (light grey). I don't have an aggressive myself, but have seen one. Hope to try one eventually and see how it does/feels compared to my +!

Or am I thinking of another razor?
